If you think you can do it, you can.
Never complain and never explain.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
Look at an infantryman's eyes and you can tell how much war he has seen.
