If you're going through hell, keep going.
It's always too early to quit.
To be a good loser is to learn how to win.
After a storm comes a calm.
Leap, and the net will appear.
Quality is not an act, it is a habit.
Know or listen to those who know.
If you've got a talent, protect it.
Expect problems and eat them for breakfast.
