Be gentle to all and stern with yourself.

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

Always desire to learn something useful.

The dog that trots about finds a bone.

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

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

It's always too early to quit.

Know or listen to those who know.

What you do today can improve all your tomorrows.
