If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Never complain and never explain.
You never know what motivates you.
The most effective way to do it, is to do it.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Quality is not an act, it is a habit.
If someday they say of me that in my work I have contributed something to the welfare and happiness of my fellow man, I shall be satisfied.
