You never know what motivates you.

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

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

After a storm comes a calm.

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

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

If you think you can do it, you can.

Know or listen to those who know.
