"By masochism I do not mean that they (masochists) get their sexual jollies out of physical pain, but simply that in some strange way they are chronically self-destructive. Masochists are people who perpetually attempt to destroy themselves. They are always, in one way or another, trying to kill themselves. In the long run they almost always succeed. Our task in therapy is to help them empty themselves of their masochism so that life may fill them instead. The problem of masochism is intimately tied up with the problem of responsibility. Masochists are people who, because they hate themselves, believe that they are worthless and deserve only punishment. They are self-destructive because they lack the capacity to assume responsibility for their own lives. Instead of taking care of themselves, they neglect themselves, abuse themselves, and in the end destroy themselves. The genuinely disciplined person, on the other hand, is one who takes responsibility for his or her own life and well-being. Discipline is self-caring. Masochism is not. Discipline is love translated into action; masochism is love turned against the self."
