If you question anything enough, you'll begin to doubt it.

Don't try to be perfect; just be an excellent example of being human.

You can use your story, or your story can use you.

People always try to be perfect. That's why they don't start anything. Perfection is the lowest standard in the world. Because if you're trying to be perfect, you know you can't be. So what you really have is a standard you can never achieve. You want to be outstanding, not perfect.

No one ever achieved a goal by being interested in its achievement. One must be committed.

I always tell people happiness comes in one word: progress. I don't care what you achieve.

Emotion is created by motion.
