You never know what motivates you.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
Do not weep do not wax indignant. Understand.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
A little learning is a dangerous thing, but a lot of ignorance is just as bad.
