Contrary to what most of us believe, happiness does not simply happen to us. It's something that we make happen, and it results from doing our best. Feeling fulfilled when we live up to our potentialities is what motivates differentiation and leads to evolution.

Purpose provides activation energy for living.

Control of consciousness determines the quality of life.

Goals transform a random walk into a chase.

Entropy is the normal state of consciousness - a condition that is neither useful nor enjoyable.

I have devoted 30 years of research to how creative people live and work, to make more understandable the mysterious process by which they come up with new ideas and new things. [...] If I had to express in one word what makes their personalities different from others, it's complexity. They show tendencies of thought and action that in most people are segregated. They contain contradictory extremes; instead of being an "individual", each of them is a "multitude".

What I "discovered" was that happiness is not something that happens. It is not the result of good fortune or random chance. It is not something that money can buy or power command. It does not depend on outside events, but, rather, on how we interpret them. Happiness, in fact, is a condition that must be prepared for, cultivated, and defended privately by each person. People who learn to control inner experience will be able to determine the quality of their lives, which is as close as any of us can come to being happy.
