It's always too early to quit.

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

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

Know or listen to those who know.

The wise does at once what the fool does at last.

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

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