It's always too early to quit.

The dog that trots about finds a bone.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.

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

If you're going through hell, keep going.

Be kind whenever possible. It is always possible.

Never complain and never explain.

Know or listen to those who know.
