Be thine own palace, or the world's thy jail.
Well done is better than well said.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
Leap, and the net will appear.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
Strange as it may seem, no amount of learning can cure stupidity, and formal education positively fortifies it.
