I think anyone's success depends on working hard, Industriousness and Enthusiasm, enjoying what you are doing. You can't work your best if you're not enjoying what you are doing. No way you can force yourself to.
A player who makes a team great is better than a great player.
Remember this, the choices you make in life, make you.
A life not lived for others is not a life, a game not played for others is not a game.
Rest when you need to, but never quit.
Make a decision! Failure to act is often the biggest failure of all.
