自由不止一种……自由去做和自由免于。在无政府状态的日子里，是自由去做。现在你被给予了自由免于。不要低估它。
There is more than one kind of freedom... Freedom to and freedom from. In the days of anarchy, it was freedom to. Now you are being given freedom from. Don't underrate it.

I don't want to be remembered for being famous. I want to be remembered for being brave.
The future is not a result of choices among alternative paths offered by the present, but a place that is created—created first in the mind and will, created next in activity.
Success is not final, failure is not fatal: it is the courage to continue that counts.
