It's always too early to quit.
Well done is better than well said.
What you do today can improve all your tomorrows.
If you can dream it, you can do it.
Never complain and never explain.
Without hard work, nothing grows but weeds.
Leap, and the net will appear.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
Quality is not an act, it is a habit.
I think America has more than enough maturity and intelligence to start exercising its world leadership responsibly.
