Never complain and never explain.
If you've got a talent, protect it.
It's always too early to quit.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
Well done is better than well said.
