Never complain and never explain.
The wise does at once what the fool does at last.
Well done is better than well said.
To be a good loser is to learn how to win.
If you think you can do it, you can.
You never know what motivates you.
Things do not happen. Things are made to happen.
The secret of getting ahead is getting started.
It's always too early to quit.
Quality is not an act, it is a habit.
But to me the bottom line is the more education you can give yourself, and the more preparation you can do, the less chance of failing.
