People are powerfully moved by imagination, belief, and knowledge. They can consider the past and future. They can make changes in their behavior out of reason, in a way that animals can’t do.

I realize that in a happy life, making your bed should play a very small part, I don't know why this is so helpful to people getting started on a happiness project, but for some reason, making your bed - it's concrete, it's manageable. There's a big difference between having a bed that's unmade and a bed that's made. That little bit of outer order in people's lives seem to help them get started. So, that's a very small thing that you can do.

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.
