The only true wisdom is in knowing you know nothing.

It's not what you are that holds you back, it's what you think you are not.

Do not judge me by my successes, judge me by how many times I fell down and got back up again.

There are two things a person should never be angry at, what they can help, and what they cannot.

A leader is best when people barely know he exists, when his work is done, his aim fulfilled, they will say, we did it ourselves.

That which does not kill us makes us stronger.

The best fighter is never angry.

If you tell the truth, you don't have to remember anything.

Always go too far, because that's where you'll find the truth.
