Be kind whenever possible. It is always possible.
Do not weep do not wax indignant. Understand.
Well done is better than well said.
After a storm comes a calm.
I can, therefore I am.
Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
If you've got a talent, protect it.
Lots of people I know have bootlegged tapes of performances and if they play it I will be transported back sometimes with happiness, sometimes with horror.
