Problems are not stop signs, they are guidelines.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
It's always too early to quit.
If you're going through hell, keep going.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
Never complain and never explain.
The most effective way to do it, is to do it.
Stronger by weakness, wiser men become.
