Be kind whenever possible. It is always possible.
After a storm comes a calm.
Either you run the day or the day runs you.
It's always too early to quit.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
Never complain and never explain.
Middle age is when your old classmates are so grey and wrinkled and bald they don't recognize you.
