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

Policy makers, like most people, normally feel that they already know all the psychology and all the sociology they are likely to need for their decisions. I don't think they are right, but that's the way it is.

Laziness is built deep into our nature.

When you look at the books about well-being, you see one word - it's happiness. People do not distinguish.

Mental effort, I would argue, is relatively rare. Most of the time we coast.

Psychologists really aim to be scientists, white-coat stuff, with elaborate statistics, running experiments.

Endlessly amused by people's minds.
