Never doubt that one person can make a difference.

I could make a difference.

Fantasy is like an idealized reality, and the core of fantasy is the one person can make a difference.

Oh, it makes a difference, I thought. And if it doesn't make a difference you will make it make a difference.

I believe in work. If somebody doesn't create something, however small it may be, he gets sick. An awful lot of people feel that they're treading water -- that if they vanished in smoke, it wouldn't mean anything at all in this world. And that's a despairing and destructive feeling. It'll kill you.

Go into the world and do well. But more importantly, go into the world and do good.
