My own child and I have had discussions that centered around mania-driven behaviors. We're not finished those discussions but we have noted that there is an emphasis on more, more, more -- whether it's new shoes, fancy meals, or sexual partners. There is an edge to mania that seems to demand satiation but the beast is fully revealed with the realization that no matter how much you feed it, true satisfaction/satiation is never reached.

It reminds me of a fairy tale I read a few years ago about a woman who longed to dance. Somehow, she got her hands on a pair of magic shoes that allowed her to dance non-stop but she soon discovered, much to her distress, that she could not take the shoes off and was forced to dance to a state of utter exhaustion.

I think mania can be like this because there seem to be such strong compellations that may appear on the surface to be enjoyable but can actually become torturous over time because you can't turn the desire for satiation off -- even if you want to, even if it is hurting you and the people you love the most.
