If you think you can do it, you can.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

It's always too early to quit.

The secret of getting ahead is getting started.

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

Never complain and never explain.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.
