Martin Seligman describes how he would like to see psychology expand to make normal people happier rather than just cure miserable people. Build on strengths instead of repairing weakness. He describes the three happy lives: pleasure, flow and meaning. He then describes how they tested those lives to find out pleasure was the least important, but like a cherry on top of the ice cream. Meaning is most important.

Martin Seligman is the founder of positive psychology, a field of study that examines healthy states, such as happiness, strength of character and optimism.
