It's always too early to quit.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
Only the educated are free.
Never complain and never explain.
You never know what motivates you.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
Know or listen to those who know.
What you do today can improve all your tomorrows.
Do you know what a soldier is, young man? He's the chap who makes it possible for civilised folk to despise war.
