If you can dream it, you can do it.
Who seeks shall find.
Quality is not an act, it is a habit.
Do not weep do not wax indignant. Understand.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
Things do not happen. Things are made to happen.
Never complain and never explain.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
