It's always too early to quit.
You never know what motivates you.
Well done is better than well said.
Who seeks shall find.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
Wherever you are - be all there.
If you've got a talent, protect it.
I found out that colonels can stay until they drop dead or get a walker and being a critical medical specialty as an Army trained emergency room doctor, I could stay until age 67.
