Napoleon Hill: "Tell the world what you intend to do, but first show it."

Don't dream of winning. Train for it.

You only fail when you stop trying.

Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work.

What seems to us as bitter trials are often blessings in disguise.

Don't let a minor distraction deter you from achieving a major goal. Know what to ignore and what to pay attention to. Use your energy wisely.
