It's good to learn from your mistakes. It's better to learn from other people's mistakes.

Blame nobody else, do not commit the mistake of the ignorant.

This is the first lesson to learn: be determined not to curse anything outside, not to lay the blame upon anyone outside, but stand up, lay the blame on yourself. You will find that is always true. Get hold of yourself.

If you hold a cat by the tail you learn things you cannot learn any other way.

Learn this from water: loud splashes the brook but the oceans depth are calm.

Praise and blame, good and bad, even heat and cold, must be equally acceptable to us.
