I can, therefore I am.

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

If you're going through hell, keep going.

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

Be kind whenever possible. It is always possible.

What you do today can improve all your tomorrows.

Things do not happen. Things are made to happen.

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