What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Always desire to learn something useful.

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

Never complain and never explain.

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.

The secret of getting ahead is getting started.
