Persistence is the great measure of individual human character.

You develop courage by acting courageously whenever you feel like acting otherwise.

The clearer you are about the consequences of your actions and the more intensely you desire to enjoy the consequences that your behaviors may lead to, the more motivated you will be.

Failure is a prerequisite for great success. If you want to succeed faster, double your rate of failure.

Aspire greatly; anything less than a commitment to excellence becomes an acceptance of mediocrity.

There are no limits on what you can achieve with your life, except the limits you accept in your mind

The more you work, study and develop your ability to contribute more to the lives and well-being of others, the better life you will have in all areas.
