I wasn't part of John Kennedy's vision of the world, or Lyndon Johnson's. I thought of them as anti-Communist imperial monsters.

I get up every morning and think, today I'm going to make a difference. Today I'm going to end capitalism. Today I'm going to make a revolution. I go to bed every night disappointed but I'm back to work tomorrow, and that's the only way you can do it.
