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.

The two hardest things to handle in life are failure and success.

Acquire peace of mind by making the effort to become the best of which you are capable.

Champions never complain, they are too busy getting better

Don't let the things you can't do get in the way of the things you can.

The importance of repetition until automaticity cannot be overstated. Repetition is the key to learning.

Respect a man, and he will do all the more.
