Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
Always desire to learn something useful.
