To know oneself, one should assert oneself.

It's always too early to quit.

Be kind whenever possible. It is always possible.

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

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

Know or listen to those who know.

The dog that trots about finds a bone.

If you think you can do it, you can.

After a storm comes a calm.
