All of us would be better investors if we just made fewer decisions.

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.

It is only a slight exaggeration to say that happiness is the experience of spending time with people you love and who love you.

Experienced happiness refers to your feelings, to how happy you are as you live your life. In contrast, the satisfaction of the remembering self refers to your feelings when you think about your life.

The effort invested in 'getting it right' should be commensurate with the importance of the decision.

By their very nature, heuristic shortcuts will produce biases, and that is true for both humans and artificial intelligence, but the heuristics of AI are not necessarily the human ones.

It's a wonderful thing to be optimistic. It keeps you healthy and it keeps you resilient.
