Self-discipline is the ability to make yourself do something you don't necessarily want to do, to get a result you would really like to have.

I will not waste time on second thoughts. My life will not be an apology. It will be a statement.

I believe that any type of education can be great, but an education about ourselves can create something wonderful. I am a comedian, but people have called me a motivational speaker. I don't really consider myself that at all.

Curiously, a principle affects your life whether you are aware of it or not. For instance, the principle of gravity was working long before the apple ever fell on Newton's head. But once it did, and he understood it, then we as a society were free to harness this principle to create, among other things, airline flight.

Truth is like a wild animal; let it loose and it will defend itself!

When you put emphasis on compromise rather than on principle, you end up with 2/3 of the principles being implemented.

In the game of life, nothing is less important than the score at halftime.
