Gretchen Rubin, author of The Happiness Project, interviews author Harlan Coben. She asked if he had a happiness mantra:
I have two mantras.
One I’ve already typed twice before: “It’s all about balance.” Family, writing, health, friends, surfing the web—whatever. They all need to be in balance. If I’m not writing well, I’m not happy. If I’m not spending enough time with my family, I’m not happy. If I’m not connecting to friends or if I don’t work out enough... You get the point. Everything has to be balanced. Nothing should be an extreme.
My second mantra is more basic: “You bring your own weather to the picnic.” My kids roll their eyes at this one, but there is no question that attitude can go a long way.
