宣传之于民主，正如棍棒之于极权国家。

I'm just trying to be better every day.

The true measure of success is how many times you can bounce back from failure.

The more I study nature, the more I stand amazed at the work of the Creator.

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.
