Water first, caffeine later: rethinking the morning coffee habit
Huberman, Matt Walker and Mel Robbins all suggest being more deliberate with caffeine, whether that means hydrating before coffee, pushing the first cup later in the morning, or cutting it off early enough to protect sleep. Small timing changes can reduce afternoon crashes and improve sleep without giving up coffee.
Why experts are cautious about using melatonin as a nightly habit
Matt Walker and Andrew Huberman both raise concerns about relying on melatonin, pointing out issues with dosing and questioning whether it is the right tool for most sleep problems. Readers reaching for a supplement habit should first understand these cautions and the behavioral alternatives.

Taylor Swift's daily idea log, Rick Rubin's honest diaries, Kevin O'Leary's sticky-note focus, and Mel Robbins' written reflection questions all show successful people putting their thoughts on paper. Daily writing clarifies priorities and captures ideas that would otherwise be lost.
21, 63, or neither: how long it really takes to build a habit
The popular 21-day rule is challenged from several sides: Caroline Leaf argues rewiring takes about 63 days, Mel Robbins calls 21 days a myth, and Huberman builds a 21-day program for a different purpose.
