It's always too early to quit.

Know or listen to those who know.

What you do today can improve all your tomorrows.

Go for it now. The future is promised to no one.

Leap, and the net will appear.

Be gentle to all and stern with yourself.

Be thine own palace, or the world's thy jail.

If you've got a talent, protect it.

To be a good loser is to learn how to win.
