It always seems impossible until it's done.

The greatest glory in living lies not in never falling, but in rising every time we fall.

First they ignore you, then they laugh at you, then they fight you, then you win.

Lead from the back and let others believe they are in front.

For a man to conquer himself is the first and noblest of all victories.

A winner is a dreamer who never gives up.
