We can't live in a state of perpetual doubt, so we make up the best story possible and we live as if the story were true.

Every night for the next week, set aside ten minutes before you go to sleep. Write down three things that went well today and why they went well...Writing about why the positive events in your life happened may seem awkward at first, but please stick with it for one week. It will get easier. The odds are that you will be less depressed, happier, and addicted to this exercise six months from now.

You are more likely to learn something by finding surprises in your own behavior than by hearing surprising facts about people in general.

We are far too willing to reject the belief that much of what we see in life is random.

Most of the moments of our life - and I calculated, you know, the psychological present is said to be about three seconds long; that means that, you know, in a life there are about 600 million of them; in a month, there are about 600,000 - most of them don't leave a trace.

I would be wary of experts' intuition, except when they deal with something that they have dealt with a lot in the past.

My interest in well-being evolved from my interest in decision making - from raising the question of whether people know what they will want in the future and whether the things that people want for themselves will make them happy.
