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.
Vince Lombardi
Winning is not a sometime thing; it's an all time thing. You don't win once in a while, you don't do things right once in a while, you do them right all the time. Winning is habit. Unfortunately, so is losing.
The only place success comes before work is in the dictionary.
Ability is what you're capable of doing. Motivation determines what you do. Attitude determines how well you do it.
