The greatest school is the University of Hard Knocks. Its books are bumps. Every bump is a lesson. If we learn the lesson with one bump, we do not get that bump again. We do not need it. We have traveled past it. They do not waste the bumps. We get promoted to the next bump. - Ralph Parlette The University of Hard Knocks' is a great big boost for everybody who will read it-and everybody ought to read it. - Judge Ben B. Lindsey.
