Expect problems and eat them for breakfast.
Always desire to learn something useful.
After a storm comes a calm.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Never complain and never explain.
Be kind whenever possible. It is always possible.
To me, all war is failure for humanity, though it often is a bounty for commerce.
