Never complain and never explain.
After a storm comes a calm.
Do not weep do not wax indignant. Understand.
If you think you can do it, you can.
Well done is better than well said.
Know or listen to those who know.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
Golf is about knowledge, and studying another player - more than listening to a teacher - is the best way to get it.
