What you do today can improve all your tomorrows.
Never complain and never explain.
Well done is better than well said.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
Go for it now. The future is promised to no one.
Only the educated are free.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
When I was about 13 or 14, I had an English teacher who made a deal with me that I could get out of doing all of the year's regular work if I would write a short story a week and on Friday read it to the class.
