Knowing what's right doesn't mean much unless you do what's right.

Know thyself.

The world is the great gymnasium where we come to make ourselves strong.

When I was in college, I wanted to be involved in things that would change the world.

Become a possibilitarian. No matter how dark things seem to be or actually are, raise your sights and see possibilities -- always see them, for they're always there.

Surround yourself only with people who are going to take you higher.

Life is 10 percent what happens to you and ninety percent how you respond to it.

I want to know what passion is. I want to feel something strongly.

My dear friend, clear your mind of cant.

Keep your eyes on the stars, and your feet on the ground.

Lack of direction, not lack of time, is the problem. We all have twenty-four hour days.

They deem me mad because I will not sell my days for gold; and I deem them mad because they think my days have a price.

Aim for the highest.

Waste no more time arguing about what a good man should be. Be one.

A thing worth having is a thing worth cheating for.

It's not what you look at that matters, it's what you see.

Believe you can and you're halfway there.

The person who takes no chances generally has to take whatever is left when others are through choosing.

Don't just read the easy stuff. You may be entertained by it, but you will never grow from it.

If my life is going to mean anything, I have to live it myself.

When I'm good, I'm very good, but when I'm bad, I'm better.
