I can, therefore I am.

If you can dream it, you can do it.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

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

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

If you think you can do it, you can.

Know or listen to those who know.

The secret of getting ahead is getting started.
