Know or listen to those who know.
Who seeks shall find.
Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
It's always too early to quit.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
If you can dream it, you can do it.
The secret of getting ahead is getting started.
If you think you can do it, you can.
If music leaves any impression at all, it does so without regard to stylistic issues.
