I find the idea of revenge too time-consuming. Karma has nothing to do with it, and like religion, karma is a flawed concept when studied under the pure light of skepticism. why do I keep saying crap like that, I am such an asshole sometimes :-). Besides, the Chinese have a proverb. “A man who seeks revenge should dig two graves before starting down that road.”
The opposite of love is not hate, it is indifference. To feel indifference towards someone who has wronged you is the ultimate revenge, and the best part is, it takes no energy whatsoever. I’ve discovered that people that have fucked me over usually end up doing more to themselves than I could ever hope to do to them with revenge.
But if you must seek revenge, then visit a book store, get as many of those little magazine order cards out of the magazines as you can find, and sign the sucker up for every magazine known to Man. Get everybody you know to save them for you, too. That is a lot of fun, and gives me a chuckle every time I do it.
