What Stoics discover, though, is that willpower is like muscle power: The more they exercise their muscles, the stronger they get, and the more they exercise their will, the stronger it gets. Indeed, by practicing Stoic self-denial techniques over a long period, Stoics can transform themselves into individuals remarkable for their courage and self-control. They will be able to do things that others dread doing, and they will be able to refrain from doing things that others cannot resist doing. They will, as a result, be thoroughly in control of themselves.
