I'm worried about the world because of nuclear proliferation.

My father, a bookkeeper who never earned more than $11,000 a year in his life, sat there, writing out a $25 check to the NAACP.

Don't be afraid to assert yourself, have confidence in your abilities and don't let the bastards get you down.

Is your company so small you have to do everything for yourself? Wait until you're so big that you can't. That's worse.
