Go for it now. The future is promised to no one.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Leap, and the net will appear.
Well done is better than well said.
If you think you can do it, you can.
Do you know what a soldier is, young man? He's the chap who makes it possible for civilised folk to despise war.
