Negative emotions like loneliness, envy, and guilt have an important role to play in a happy life; they’re big, flashing signs that something needs to change.

Writing makes me happy.

I'm doing a lot of speaking and talking about habits, which is this subject that obsesses me. That's a lot of fun.

I have a passion for children's literature. Young adult literature. I love it. I've always loved it.

Feelings follow actions. If I'm feeling low, I deliberately act cheery, and I find myself actually feeling happier. If I'm feeling angry at someone, I do something thoughtful for her and my feelings toward her soften. This strategy is uncannily effective.

I am living my real life, this is it. Now is now, and if I waited to be happier, waited to have fun, waited to do the things that I know I ought to do, I might never get the chance.

It was time to expect more of myself. Yet as I thought about happiness, I kept running up against paradoxes. I wanted to change myself but accept myself. I wanted to take myself less seriously -- and also more seriously. I wanted to use my time well, but I also wanted to wander, to play, to read at whim. I wanted to think about myself so I could forget myself. I was always on the edge of agitation; I wanted to let go of envy and anxiety about the future, yet keep my energy and ambition.
