The Big Picture
The message running through these conversations is that struggling to change is a problem of method, not of character. Mel Robbins opens one solo episode with exactly that: if you have struggled to change your behavior, you are not the problem; the problem, she argues, is that most people have never been taught the simple, science-backed systems that make new behaviors stick [4]. Andrew Huberman reaches the same place through biology. Habits are learned behaviors, not hard-wired reflexes [5], learned patterns of neural activity that can be deliberately built and dismantled [1], and he says it's estimated "up to 70% of our waking behavior is made up of habitual behavior." [5]
Goals get the same treatment. Cognitive scientist Maya Shankar tells Huberman that small changes in how we frame goals have outsized effects [3]. Robbins, drawing on research from psychologist Elliot Berkman at the University of Oregon, breaks goals into two required components, the will and the way [6]. Wharton's Katy Milkman, on The School of Greatness, explains fresh starts: at chapter breaks in our lives we step back and think big-picture [7].
Where the Experts Agree
- A habit is a pattern you can redesign. Huberman calls habits learned patterns of neural activity [1]. Robbins wants listeners to drop the fancy word habit and think about patterns, asking simply how to make a pattern automatic [2]. She breaks every habit into three parts: the trigger, the behavior and the reward [4].
- Missing a day is not failure. Huberman's 21-day system sets six habits with an expectation of four or five and no compensating for misses [1]. Robbins covers the habit research on slip-ups and the "what the hell" effect under the heading that missing a day is not failure [2]. Milkman explains why flexible habits beat rigid ones [7].
- Identity is part of it. Robbins says the vision of who you want to become matters more than what you should do [2]. Shankar talks about anchoring identity to your why [3]. Milkman says that at chapter breaks we feel a shift in identity that lets us separate ourselves from past failures: the old me couldn't do it, but this is the new me [7].
- Plans beat intentions. Robbins's fourth system is to create a plan, including if-then plans [2], and if-then plans are among the tools Milkman explains [7]. Huberman recommends visualizing the steps of a habit [1].
- Timing matters. Huberman places the hardest habits in the high-alertness first phase of the day and easier ones in the calmer second phase [1]. Robbins's fifth system is to do it in the morning, which she calls the first domino [2].
- Rewards drive the loop. Huberman says to reward the whole sequence around a habit honestly rather than just the act itself [1]. Robbins explains the habit loop and dopamine [4], and Shankar notes that succeeding at an approach goal produces pride and boosts motivation and perseverance [3].
Where They Differ
The speakers largely agree; they differ in where they put the weight.
Inside the body or outside it. Huberman's tools start with the nervous system: phases of the day, protecting sleep so the learning consolidates, and concepts such as limbic friction, linchpin habits and task bracketing [1][5]. Robbins works on the surroundings. She says keeping change in your head fails and external cues work: sticky notes, laid-out clothes, a restocked fridge and labeled phone alarms [2].
How to break a bad habit. Huberman suggests immediately following the bad habit with a simple positive action, rewriting the circuit from the end rather than the beginning, rather than relying on reminders or punishment [1]. Robbins's second system is to remove temptation, such as getting the phone out of the bedroom [2], and she offers ways to replace bad habits [4].
Tracking and telling. Robbins recommends tracking progress with a Post-it grid, streaks and public reporting [2]. Huberman's system ends instead with a test period to see what truly stuck [1].
Who sets the goal. Shankar says people will go to irrational lengths to preserve agency, even preferring their own judgment over a better-performing algorithm, and suggests asking coaches and managers for a set of options so you own your targets [3]. Huberman adds that when he let lab members set their own paper deadlines, they consistently beat them [3].
What starts a change. Howes suggests that big breakdowns, like a loss or a near-death experience, often drive change; Milkman says survey research suggests such shocks create identity shifts through the same mechanism, but positive milestones can too [7]. She also cautions that research has not yet wrapped its arms around identity as well as she would like [7].
Practical Takeaways
- Put your hardest habits in the first phase of the day and easier ones in the second, as Huberman advises [1].
- Try his 21-day system: six habits, expect to do four or five, and don't compensate for misses [1].
- Make the cue visible: sticky notes, laid-out clothes, a restocked fridge or labeled phone alarms [2].
- Get the phone out of the bedroom to remove temptation [2].
- Frame goals as something to approach (eat healthier foods), not something to avoid (avoid junk food), as Shankar describes [3].
- Ask a coach or manager for a set of options so the target is your own [3].
- To break a bad habit, follow it immediately with a simple positive action [1].
- Plan ahead and write an if-then plan, a tool both Robbins and Milkman cover [2][7].
