Know or listen to those who know.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
I can, therefore I am.
Quality is not an act, it is a habit.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.
