Everyone has a 'risk muscle.' You keep it in shape by trying new things. If you don't, it atrophies. Make a point of using it at least once a day.

Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.

Take advantage of the ambiguity in the world. Look at something and think what else it might be.

Failure is not an option.

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

The human body has two ends on it: one to create with and one to sit on. Sometimes people get their ends reversed. When this happens they need a kick in the seat of the pants.
