Well, what I enjoy about it is that I feel more alive, more witty, more charming, and more entertaining. My mood is elevated, and if I have an "audience" I can apply my talent for theatricality to amuse both them and myself. At times when it doesn't amuse others, it still amuses me.
I'm craving the ability to express myself creatively. But in the absence of ways to do that, I take the opportunity when I'm in a manic mood to stretch those performance muscles in everyday situations. So that's why I enjoy it. Really only the depression gets to me.
