Be kind whenever possible. It is always possible.

Never complain and never explain.

Either you run the day or the day runs you.

Things do not happen. Things are made to happen.

Well done is better than well said.

What you do today can improve all your tomorrows.

Be thine own palace, or the world's thy jail.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.
