Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
Do not weep do not wax indignant. Understand.
If you think you can do it, you can.
Never complain and never explain.
Well done is better than well said.
Things do not happen. Things are made to happen.
My first three years of high school, I wasn't that cool.
