Cut before you optimize: why productivity starts with elimination

The Short Version

Before you buy a new app, build a new system or learn a faster way to work, decide what you will stop doing. Jonathan Fields calls discernment the biggest optimizer: find the task that eats 40% of your time and gives back 2% of what you care about, and remove it [1]. Greg McKeown's Essentialism makes elimination the middle step of a three-step method, placed after working out what matters and before execution, with its systems and routines [2]. Mel Robbins' weekly reset starts the same way: dump everything out of your head, then cross off, without guilt, everything that isn't happening this week, and only then choose one thing to schedule [3]. Efficiency applied to a bloated list only gets you through the wrong things faster. The cut comes first, and it is often harder than it looks, because busyness can feel safer than stillness [4].

What They Said

Jonathan Fields: optimize your "discernment engine," not your tasks

Jonathan Fields is a former securities lawyer, founder of Good Life Project and author of Sparked. His view of productivity was shaped by a collapse. In the 1990s, working 100-hour weeks at a big firm and sometimes not going home for days, his immune system gave out and an infection ate a hole through his intestine, which sent him into emergency surgery [1]. After that he kept asking how to do work differently, in a way that feels meaningful and alive [1]. His diagnosis of burnout isn't mainly about hours. He argues that burnout has been rising for 10 to 15 years, because many people spend their days on work that doesn't match what actually nourishes them [1].

When Lewis Howes turned the conversation to productivity, Fields described himself as a meta-thinker who is always looking for levers [1]. He doesn't dismiss efficiency: "There's strategies that you can use to optimize what you're doing every day to make it more efficient, quicker. And those will make differences." But then he turns: "the bigger issue is, what should I just not be doing at all?" [1]

His test is a simple ratio: "What is the thing where it's taking 40% of my time? But, you know, it's only contributing 2% to whatever outcome that I genuinely care about in my life, in the work, you know, or whatever's being measured." [1] Asking that question, he says, is how "we gain the ability to understand what really matters and what to focus on," rather than looking at everything we do and asking how to optimize all of it [1]. He sets that against the reflex to reach for tools. The wrong question is "what's the technology?"; the right move is to "Zoom the lens out and, like, optimize your discernment engine and understanding what, you know, truly matters." [1]

He measures the lever two ways, by outcomes and by feeling: "What is the big lever in whatever metric is being measured and in the way that I want to feel?" [1] The conversation then states the principle outright: "eliminating tasks that aren't meaningful is the biggest way to multiply your time." [1]

Fields also makes a distinction that stops elimination from becoming a fantasy. Removing something from your plate doesn't mean it stops needing to be done. Talking about how Howes runs his team, the point is that there are necessary tasks, "But it doesn't necessarily mean like you should be the one doing them and then optimizing to do them better." [1] That is the trap the insight describes. You take a task you shouldn't be doing at all and make yourself faster at it.

Lewis Howes: cut, then guard the space

Howes gave a concrete example. Matt on his team replaced two weekly meetings with an email debrief, which freed about an hour that Howes now spends on interview prep and networking [1]. He described asking his team, "what can I do to, like, eliminate more and more things? Just focus on the thing that I'm really good at. And how do I double down on those things?" His aim is to multiply "impact, income, all that stuff" and to "feel more fulfilled in my work as well." [1]

He also warned that time you free up doesn't stay free. Left alone, it fills with email and social media, so he deliberately schedules free time and idea time [1]. Fields does the same. His calendar is dotted with "KF blocks, which means keep free." [1] He gave an example of how easily the unscheduled gets lost. While staying in Santa Monica, he realized he had gone days without visiting the ocean three blocks away. So he reorganized his schedule to end each day walking by the water and meditating at sunset [1]. The order matters here. Cutting makes the space, and protecting it on the calendar keeps it.

The same episode shows why elimination sometimes means more than trimming a to-do list. Howes described eczema that lasted months, even though his blood work and allergy tests came back normal. It cleared within days once he stopped doing things he felt were out of integrity with himself: "the moments that I, that I eliminated those things for my life and just said, okay, I'm not doing this anymore. I'm not abandoning myself." [1] Fields, who says clearly that he is not a doctor, says his body is his "tell" under psychological or existential stress, even when his mind feels fine [1]. For both men, what you cut isn't only low-value tasks. It can be commitments that don't fit who you are.

Fields' Sparketypes: know which work drains you

Fields' Sparketype framework gives the elimination question a personal angle. Each person has a primary impulse for work that makes them come alive, a "shadow they do in service of the primary, and an anti-Sparketype": "your weakest impulse or the thing that empties you the most, takes the greatest amount of recovery." [1] His team built an assessment that about 500,000 people have now taken [1].

The anti-Sparketype that Fields and Howes share is the Essentialist, the impulse "to create order from chaos. It's about systems. It's about process." [1] (It's a different thing from McKeown's Essentialism, which is about choosing less.) Howes said that when he looks at the roughly 40 episodes his show has in production at any time, "I just want to cry," while his producer, an Essentialist, looks at the same chaos and says, "I want to build out these. systems. I want to run them. I want to optimize them." [1] Fields concludes that "when you're not an essentialist, having to do the work of an essentialist is experienced generally as not fun in a really big way." [1] Knowing your anti-Sparketype, he says, removes shame, because draining work stops feeling like proof that you are lazy [1]. It is also a map of what to hand off. The work that drains you most is the first to delegate or redesign, not something to drill yourself into doing faster.

Greg McKeown's Essentialism: explore, eliminate, then execute

Perfect Summary's breakdown of Essentialism: The Disciplined Pursuit of Less sums up McKeown's thesis as: doing more does not mean achieving more [2]. The book opens with the warning that if you don't prioritize your life, someone else will, and it presents Essentialism as a way of life rather than a productivity tactic [2]. The aim is to make your highest possible contribution to the things that matter by deliberately saying no to everything that doesn't [2].

The book's structure puts the insight into three steps [2]:

• Explore. Pause and reflect, ask what really matters, and make room for discernment instead of reacting to everything. Essentialists spend more time listening, observing and clarifying before they commit [2].
• Eliminate. Once you know what's essential, cut the rest. McKeown treats "no" not as rejection but as a tool of protection: saying no is what lets you say yes to your highest point of contribution [2].
• Execute. With fewer distractions, do what matters with focus and excellence, using routines, protected time and systems designed so execution becomes effortless [2].

Systems do appear in McKeown's method, but only in the third step, applied to a list that has already been cut. They make the essential few effortless. They aren't meant to make the whole pile manageable.

McKeown's supporting principles add sharper tools. The 90% Rule: if something doesn't score at least 90 out of 100 in importance, eliminate it [2]. Buffer Time: build in margins so you aren't always running at the edge of burnout [2]. Protect the Asset: the asset is you, and sleep, rest and space are requirements for meaningful contribution, not luxuries [2]. He calls the belief that we can do it all a myth that leads to exhaustion and mediocrity, and argues for trade-offs instead: conscious choices to focus on less so you can contribute more [2].

He also makes clear that this isn't a one-time purge. Essentialism takes continual reevaluation of what is truly vital, and a willingness to disappoint others in order to honor your own path [2]. Simplicity isn't easy, it's deliberate. Essentialists aren't lazy or passive but intensely focused; they don't just do things right, they make sure they're doing the right things [2]. It isn't about saying no to everything either. It's about saying yes to what really matters [2].

Mel Robbins: brain dump, then free yourself

Mel Robbins' seven-item weekly checklist comes from what she describes as a decade of researching and teaching about happiness, productivity and focus. It starts from the same place [3]. Her diagnosis: "the world is now designed to steal your time, your energy, your joy and your focus," through doom-scrolling, alarming headlines, endless work and never-ending to-do lists [3]. Without a plan for what matters, she says, you end up with days "filled with this meaningless nonsense or other people's emergencies or your energy drained by stupid stuff." [3]

Her first step, the brain dump, gets everything in your head onto paper. She calls it the equivalent of mental vomiting [3], and her upgraded version uses three large Post-it notes labeled work, personal and home, left out all weekend so items can be added as they come up [3]. She insists a brain dump is not a to do list. She has no intention of doing most of it; the point is simply to get it out of her head [3]. Looking at her home list, she realized how much of it wasn't happening that week: "And yet I'm carrying it around in my head." She wasn't going to organize her bathroom drawers or clear out the pantry [3].

Item two is where the elimination happens. "You're going to free yourself," she says. "This is the most liberating thing in the world. You are going to cross things off. There is so much on that list that you have zero intention of doing this week." [3] Take a Sharpie and wipe it off the list: "That's where you're going to free yourself of the burden of carrying this around." [3] Her instruction: Cross it off zero guilt. [3] Her example is a FedEx box of old photos, including one from her 1986 college drop-off, that has sat by her desk for four or five years. She says she drags it around mentally like a "tractor trailer." [3] Bookcases, junk drawers, donation bags and the garage all go too: "These projects are not getting done." [3] She says that without this step she would have spent her upcoming flight to Los Angeles thinking about everything she "should" be doing [3]. Crossing things off gets that mental energy back and puts you in control, which she frames as fighting back against a world built to drain you [3].

She admits the cut isn't clean. Some items you "can't quite press it off. Can't quite set myself free." [3] Only after crossing off does she add anything. From what's left, you circle one item that matters to you personally, not to work, family or parents, and schedule a "hot 15 for it: fifteen minutes of progress, because it's not real until it's scheduled" and "If it's not in your calendar, it's not happening." [3] She warns that without this step "the world will steal meaning from you as well." [3] Her own circled item, after four years on every brain dump, was the picture wall. Four years into living in her Vermont house, no family photo hung on any wall. In fifteen minutes she searched for picture-wall services, found a store in Boston and booked a four-hour appointment [3].

The rest of the checklist sticks to the same minimalism. She asks for one meal, one workout, one moment of phone-free rest and one connection, not a full overhaul [3]. She admits each looks like "a low bar on the surface, and argues that the research behind them shows why they matter, and that most people aren't doing them [3]. Her summary of the whole thing: First brain dump free yourself by crossing it off. Choose one thing and schedule the hot 15." [3]

Dr. Scott Lyons: why the cut is so hard

In a separate Mel Robbins episode, somatic psychologist Dr. Scott Lyons explains why eliminating commitments can feel almost impossible, even when it's obviously the right move [4]. He argues that busyness is often not about getting things done at all: "Busyness is often an avoidance strategy. It's how we stay out of contact with our own pain, vulnerability, or unprocessed emotions." [4] Every to-do list and overpacked calendar may be a way of not having to sit with yourself [4].

He traces this to childhood. If you only got attention when you performed, achieved or pleased others, you may have learned the belief "I am valuable when I am doing something." [4] He adds a biological layer: constant doing delivers small dopamine rewards, and stopping makes the nervous system panic, because stillness feels unsafe; over time your baseline becomes activation [4]. He also makes a pointed claim about output: busy people aren't necessarily productive people. "They're often hyper-focused in one area of life while the rest is falling apart—relationships, health, rest, home." [4]

That explains why a list keeps growing. If motion itself is regulating you, crossing things off feels like a threat, not a relief. His prescription starts with the pause: "What happens when you pause?" [4] He suggests sitting for 2 to 5 minutes without stimulation, standing in line without your phone, and building a stillness ritual. When the urge to fill the space comes, he asks, "What am I running from right now?" [4] His reminder for a nervous system stuck in the past: "That was then. This is now." [4]

Where They Agree, and Where They Don't

The core agreement. All three main voices put subtraction before improvement. Fields says the bigger issue than efficiency is what you shouldn't be doing at all [1]. McKeown places Eliminate between Explore and Execute, so systems and routines only apply to what survives the cut [2]. Robbins has you cross off before you circle and schedule anything [3]. Each also warns that the world will fill an unguarded life. McKeown says someone else will prioritize your life if you don't [2]. Robbins says the world will steal your time, your energy and even your meaning [3]. Howes says freed time fills with email and social media [1].

They agree that elimination is a practice, not a single event. McKeown calls for continual reevaluation [2]. Robbins' checklist is weekly by design, and she says you can come back to it "over and over and over again." [3] Fields' "KF" blocks and Howes' scheduled idea time are standing defenses, not one-off cleanups [1].

They differ on what counts as "the cut." The three work at different scales. Robbins' crossing-off is often temporary and guilt-free: the bookcase or the box of photos isn't abolished, just released for this week [3]. McKeown's 90% Rule is harsher and more permanent: anything below 90 out of 100 in importance should go [2]. Fields works at the level of a whole career. His question covers low-value tasks, but also work misaligned with your Sparketype, and in Howes' case, commitments he felt were out of integrity with himself [1].

They differ on who does the cut work. Fields and Howes both lean on delegation: a task may still need to be done, just not by you [1], and a producer who loves systems can own the chaos that makes Howes want to cry [1]. McKeown's summary talks more about saying no and accepting that you'll disappoint people [2]. Robbins' reset is mostly individual: it's your brain dump and your Sharpie [3].

Systems aren't the enemy, just the wrong starting point. None of them is against structure. McKeown's third step is all about routines and systems that make execution effortless [2]. Fields cites Katie Milkman's behavior-change research to argue that success isn't only willpower, and that you can build relationships, environments and default states that make the right actions automatic [1]. Robbins' tricks, such as calendar alarms, and pasting the link to a streamed workout class into the calendar event, are small systems [3]. The disagreement with conventional productivity advice is about order, not whether systems belong at all.

Lyons adds a friendly complication. The other sources treat elimination mostly as a question of judgment: see clearly, then cut. Lyons suggests that for many people the obstacle isn't clarity but the nervous system. They may know exactly what to cut and still be unable to stop, because busyness is doing emotional work for them [4]. His view doesn't contradict the others. It explains why their advice can be hard to follow.

Why It Works

The sources give several reasons why cutting first beats optimizing first.

Leverage. Fields' 40%/2% example is about proportions. Making a task 20% faster still leaves it consuming most of your time for almost none of your results. Removing it frees the full 40% [1]. That's why, as the conversation put it, eliminating meaningless tasks is "the biggest way to multiply your time." [1]

Trade-offs are unavoidable. McKeown argues that trying to do it all leads to exhaustion and mediocrity [2]. Because every yes costs something, saying no is what protects your highest point of contribution [2]. Buffer time and protecting "the asset" (you) matter because running constantly at the edge of burnout erodes the very capacity you're trying to use [2].

Mental load. Robbins' method rests on the idea that unmade decisions take up space. Every item written down frees a little mental space, and you'll be surprised how much you've been carrying and why you couldn't focus [3]. Crossing things off gets that energy back; skipping it means spending a flight on all the things you "should" be doing [3].

Progress on the few beats motion on the many. Robbins grounds her one-thing step in Harvard Business School research. People across seven companies kept work journals, about 12,000 entries in all, and the most common trigger of their best days was making progress on meaningful work, not finishing a project [3]. Small progress brings positive emotion, pride and a natural motivation to keep going [3]. You can only get that progress if the meaningful item isn't buried under everything else. She also notes that once you start, fifteen minutes often turns into thirty or forty, because getting started is the hard part [3].

Alignment and the body. Fields' broader argument is that burnout comes less from hours than from misalignment, which over time becomes outright conflict [1]. Cutting what doesn't fit, especially your anti-Sparketype work, reduces that friction in a way no efficiency tool can [1]. Both he and Howes describe physical symptoms that eased once they changed what they were doing, though they offer these as personal experience, not medical findings [1].

The addiction loop. Lyons explains why bloat keeps coming back: doing delivers dopamine hits, stillness triggers alarm, and activation becomes the baseline, with poor sleep, constant tension and emotional reactivity as the result [4]. Cutting commitments without dealing with that loop can simply clear space for new busyness, which matches Howes' warning that freed time fills itself [1][4].

Where It Applies, and Where It Doesn't

It applies most when your list is long and your results feel thin: the 40%/2% situation [1]. It applies when you already feel on the edge of burnout; McKeown's buffer-time and protect-the-asset principles and Fields' burnout research both point to subtraction [1][2]. It applies to home and personal lists as much as to work, as Robbins' bathroom drawers, bookcases and garage show [3]. And it applies when you're doing work that drains you, where handing off or redesigning your role beats grinding harder [1].

It doesn't mean everything can go. Fields is clear that some tasks still need doing, just not necessarily by you [1]. People without a team to delegate to have fewer options; Robbins' version, which releases items for a week rather than abolishing them, may fit their situation better [3]. McKeown admits that choosing your own path will sometimes mean disappointing others [2].

It doesn't replace systems. It sequences them. McKeown's Execute step and Fields' use of Milkman's scaffolding research show that structure still matters once the list is right [1][2]. Robbins adds new commitments (a meal, a workout, rest, a connection) after the crossing-off, deliberately kept to one of each [3].

It doesn't work if the space isn't protected. Without "KF blocks or scheduled idea time, freed hours go to email and social media [1]. Robbins makes the same point: If it's not in your calendar, it's not happening." [3]

It may not stick if busyness is serving an emotional purpose. Lyons argues that for some people constant doing is a way to avoid pain, and that stillness sets off their nervous system [4]. For them, the first step may be learning to tolerate a pause before they can tolerate a shorter list [4]. Fields notes that anyone dealing with mental illness or serious emotional struggle should seek professional help [1]. If exhaustion, anxiety or physical symptoms persist, talk to a doctor or a qualified mental-health professional rather than treating it as a scheduling problem.

What To Do With It

1. Do a full brain dump before planning anything. Use three sheets or Post-its labeled work, personal and home, and leave them out for a day or a weekend so forgotten items can surface. Remember it's not a to do list. [3]

2. Cross off everything that isn't happening this week, with zero guilt. Use a thick marker if it helps you mean it. Box of old photos, bookcase, garage: release them for now [3].

3. Run Fields' ratio on your regular commitments. For each recurring task or meeting, estimate how much of your time it takes and how much it contributes to outcomes you actually care about. Anything like 40% of your time for 2% of the result is the first thing to remove, not to speed up [1].

4. Apply McKeown's 90% Rule to new requests. If something doesn't score at least 90 out of 100 in importance, say no. Treat "no" as protection for your highest contribution [2].

5. Ask should I be the one doing this? before how do I do this faster? Replace meetings with written updates where you can, as Howes' team did with an email debrief that freed an hour [1]. Hand off the work that matches your anti-Sparketype to someone who's energized by it [1].

6. Choose one meaningful thing and schedule a hot 15. From what survives the cut, circle one item that matters to you personally and put fifteen minutes of progress on your calendar with an alarm. Aim for progress, not completion [3].

7. Put free time on the calendar before anything else fills it. Block "KF" (keep free) time and idea time, and build buffers between commitments so you aren't operating at the edge [1][2].

8. Only then add systems. Once the list is short, design routines and default settings that make the essential few automatic, as in McKeown's Execute step and Milkman's scaffolding [1][2].

9. Notice what happens when you pause. If you can't cross anything off, try Lyons' experiments: sit for 2 to 5 minutes without stimulation, stand in line without your phone, and ask "What am I running from right now?" [4]

10. Repeat weekly. Elimination is ongoing. Make the reset a standing ritual, ideally on the weekend, so the list never gets back to its bloated state [2][3].
