Courage

I would rather be free in my mind, and be locked up in a prison cell, than to be a coward and not be able to say what I want.

You should never wear your best trousers when you go out to fight for freedom and truth.

When you innovate, you've got to be prepared for everyone telling you you're nuts.

Cowards die many times before their deaths; the valiant never taste of death but once.

It always seems impossible until it's done.

I learned that courage was not the absence of fear, but the triumph over it.

The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.
