No pessimist ever discovered the secret of the stars, or sailed to an uncharted land, or opened a new doorway for the human spirit.
He who angers you conquers you.
How much more grievous are the consequences of anger than the causes of it.
If you are patient in one moment of anger, you will escape a hundred days of sorrow.
It is not fair to ask of others what you are not willing to do yourself.
Do to others what you would have them do to you.
People will judge you by your actions, not your intentions. You may have a heart of gold, but so does a hard-boiled egg.
Discretion is being able to raise your eyebrow instead of your voice.
He is able who thinks he is able.
Would ye both eat your cake and have your cake?
