If you think you can do it, you can.
Quality is not an act, it is a habit.
Things do not happen. Things are made to happen.
Never complain and never explain.
If you've got a talent, protect it.
It's always too early to quit.
If you can dream it, you can do it.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
Our citizens and those who have gone before us charted the broad outlines of where we need to go, and they would envy our opportunity to translate those dreams into action. And I believe they will judge us very harshly should we fail to act.
