" But disappointment in pleasure is a completely different thing. While pain can often be seen as a means to a greater end, pleasure is seen as an end in itself. And when pleasure has run its course, a sense of despondency can creep into one’s soul that may often lead to self-destruction. Pain can often be temporary, but disappointment in pleasure gives rise to emptiness—not just for a moment, but for life. "
