Self-help ✦ Penny’s Take
Making Habits, Breaking Habits
Jeremy Dean · 2013
76/100
👍 Worth It
Jeremy Dean does real homework here, pulling from hundreds of studies to bust the tired '21 days' myth and show what actually rewires a habit. The first stretch reads more like a psych lecture than a pep talk, but if you stick with it the practical tools for building routines and dropping bad ones are genuinely useful.
