The dog that trots about finds a bone.

It's always too early to quit.

The wise does at once what the fool does at last.

I can, therefore I am.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

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

Never complain and never explain.

What you do today can improve all your tomorrows.
