Entrepreneurs constantly confuse what they do with who they are.

Ability is the result of mental and physical toughness, resourcefulness, and powerful concentration.

You get what you work for, not what you wish for.

Failure is important because the first time you win (or lose), it could be luck, it could be timing, or it could be talent. It's only after you fail once or twice and learn to rely equally on thought, analysis, and anticipation-in addition to speed, talent, and execution-that you can really call yourself an entrepreneur ... In the long run, it's mind over muscle, strategy over strength, and a healthy perspective-not just a lot of perspiration-that make someone a real success in his or her business and in the equally important rest of his or her life.

If you’re worrying about the past, you’ve got a good chance of screwing up the future.

Entrepreneurs constantly confuse what they do with who they are. We're all certainly responsible for what we do, but failing doesn't make us bad people and succeeding doesn't make us omniscient.
