Positive thinking is powerful stuff: It can keep you calm, reduce your stress hormone (cortisol)—and even make your workouts more effective. (Seriously.) Happy thoughts can also help develop your prefrontal cortex—AKA the area of your brain that supports creativity. Sounds heady, but the practice itself could be as simple as reciting a mantra or affirmation.

There are ancient ones such as “sat nam” (“truth identified”), which Kundalini yogis (like self-help guru and Well+Good Council member Gabrielle Bernstein) swear by. Or more modern options like, IDK, #iamwellandgood. It’s all about finding what works for you. And one of the best ways to do this is by hearing the sayings others find helpful.
