Life, never deciding to master anything in particular.

Obstacles are merely a call to strengthen your resolve to achieve your worthwhile goals.

My definition of success is to live your life in a way that causes you to feel a ton of pleasure and very little pain - and because of your lifestyle, have the people around you feel a lot more pleasure than they do pain.

Feed and strengthen your body. Fear is physical. When you lift weights or go for a sprint, that energy flows back into your body and restores you to certainty.

Success leaves clues. Go figure out what someone who was successful did, and model it. Improve it, but learn their steps. They have knowledge.

In order to be happy, human beings must feel they are continuing to grow. Clearly, we must adopt the concept of continuous improvement as a daily principle.

Things are only impossible until somebody does what another believes can't be done.
