It's said that a wise person learns from his mistakes. A wiser one learns from others' mistakes. But the wisest person of all learns from others's successes.
John C. MaxwellPeople who blame others for their failures never overcome them. They simply move from problem to problem. To reach your potential, you must continually improve yourself, and you can't do that if you don't take responsibility for your actions and learn from your mistakes.
