Never complain and never explain.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
Know or listen to those who know.
I can, therefore I am.
The secret of getting ahead is getting started.
The wise does at once what the fool does at last.
It's always too early to quit.
Attempt something so impossible that unless God is in it, it's doomed to failure.
