Let’s take a very simple example: you want to lift a heavy weight. All the potential energy in your physical body is mobilized: muscles, heart, lungs and even the brain take part in this action. But if you do not have the will to do anything, all your organs stagnate and become sluggish. It is your will to work that mobilizes all your potential. By expending some effort, a criminal can end up surpassing the most virtuous of people in generosity, patience and kindness. Meanwhile those with ability often achieve nothing of note, because they are good just as they are, they don’t think about working."
