So that morning in 1962 I told myself: Let everyone else call your idea crazy . . . just keep going. Don’t stop. Don’t even think about stopping until you get there, and don’t give much thought to where “there” is. Whatever comes, just don’t stop.

The world is in a constant state of flux. Nothing remains the same from one moment to the next. You can never step into the same river twice.

I don't need a reason to be bold.

人生苦短，必须快乐。
