Know or listen to those who know.

To know oneself, one should assert oneself.

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

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

If you can dream it, you can do it.

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

Never complain and never explain.
