MAKING HABITS, BREAKING HABITS: Why We Do Things, Why We Don't, and How to Make Any Change Stick, by Jeremy Dean. Da Capo Lifelong, 264 pp., $26.

You've probably read that it takes only 21 days to create a new habit. But science hasn't substantiated that figure, writes Jeremy Dean, creator of PsyBlog, a website analyzing psychological studies. New research says that cementing a simple habit, like drinking a glass of water after breakfast, might take 21 days, but a more complicated one could take nearly a year.
