Every day I am on this Earth, I will do all I can for so many important causes.

I can't stand Tiger Woods. He is the most selfish man I've ever played golf with.

I'm just a regular guy.

As you know, I'm all about victory for the underdog.

They say people live to be happy. If you actually think about what happiness is, it's nothing much. When you get to eat ramen after feeling really, really hungry, that's happiness.

I used to hold a unitary view, in which I proposed that only experienced happiness matters, and that life satisfaction is a fallible estimate of true happiness.

I have always been a great believer that women should support women, and my admiration goes out to mothers everywhere, as they constantly put their own needs behind those of their children, embracing daily uncertainties and entering the new uncharted territories that each day brings, to be, in return, rewarded with joy and unending love.

Our species uses music and dance to express various feelings: love, joy, comfort, ceremony, knowledge, and friendship. And each one is distinct and widely recognized within cultures. Love songs cause us to move slowly and fluidly, for example, while songs of joy inspire us to dance in a full-body aerobic way.
