Never complain and never explain.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
Go for it now. The future is promised to no one.
