Never complain and never explain.

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

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

Always desire to learn something useful.

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.
