The belief that unhappiness is selfless and happiness is selfish is misguided. It's more selfless to act happy. It takes energy, generosity, and discipline to be unfailingly lighthearted, yet everyone takes the happy person for granted. No one is careful of his feelings or tries to keep his spirits high. He seems self-sufficient; he becomes a cushion for others. And because happiness seems unforced, that person usually gets no credit.

The most reliable predictor of not being lonely is the amount of contact with women. Time spent with men doesn't make a difference.

Pay close attention to any flame of enthusiasm.

It's about living in the moment and appreciating the smallest things. Surrounding yourself with the things that inspire you and letting go of the obsessions that want to take over your mind. It is a daily struggle sometimes and hard work but happiness begins with your own attitude and how you look at the world.

We are happy when we are growing.

Enthusiasm is more important to mastery than innate ability.

Laughter is more than just a pleasurable activity...When people laugh together, they tend to talk and touch more and to make eye contact more frequently.
