The Perfect Revenge
In case you haven't frequented "What Makes Narcissists Tick" long enough to notice the difference, I should mention that when I started, I wasn't serious about the book. (Not like I was about my other books.) It was just an easy-on-the-eyes version of the Website, especially for people on dial-up connections. I almost felt guilty about charging money for it.
But over time, I have gotten better. Comforting others has comforted me and made me neither selfless anymore nor selfish. And I find it the perfect revenge to get something positive out of contact with the narcissists in my life.
I could almost thank them for this income stream.
(But I won't ;-)
