To know oneself, one should assert oneself.

Always desire to learn something useful.

Know or listen to those who know.

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

If you think you can do it, you can.

Things do not happen. Things are made to happen.

The secret of getting ahead is getting started.

Go for it now. The future is promised to no one.

The dog that trots about finds a bone.
