Someone's sitting in the shade today because someone planted a tree a long time ago.

Put your heart, mind, and soul into even your smallest acts. This is the secret of success.

Change your thoughts and you change your world.

Every heart that has beat strongly and cheerfully has left a hopeful impulse behind it in the world, and bettered the tradition of mankind.

Nurture your minds with great thoughts. To believe in the heroic makes heroes.

What great thing would you attempt if you knew you could not fail?

I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion.

It is only in sorrow bad weather masters us in joy we face the storm and defy it.

Thought is the wind, knowledge the sail, and mankind the vessel.

I am prepared for the worst, but hope for the best.
