It's always too early to quit.

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.

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

You never know what motivates you.

Expect problems and eat them for breakfast.

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.
