If you think you can do it, you can.

If you're going through hell, keep going.

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

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

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

Things do not happen. Things are made to happen.

Know or listen to those who know.

Always desire to learn something useful.
