The measure of who we are is what we do with what we have.

Practice does not make perfect. Only perfect practice makes perfect.

The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack of will.

The harder you work, the harder it is to surrender.

Many more things would be accomplished if we didn't consider them impossible.
