I would say to young entrepreneurs and budding philanthropists - are you giving to feel good or do good?

People feel good about giving money to Greenpeace.

When you feel good is when you're not afraid to feel the worst.

I often say fame is kind of like a drug or like sugar: when it's controlling you it doesn't feel good at all.

I don't judge others. I say if you feel good with what you're doing, let your freak flag fly.

When I do good, I feel good. When I do bad, I feel bad. That's my religion.
