By failing to prepare, you are preparing to fail.
Do not weep do not wax indignant. Understand.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
The secret of getting ahead is getting started.
Never complain and never explain.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
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.
