It's always too early to quit.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

If you've got a talent, protect it.

If you're going through hell, keep going.

If you can dream it, you can do it.

Know or listen to those who know.

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

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