I think about the smart/stupid happy/sad thing a lot too.
I'd trade half of my IQ just to be content with being alive.
But then again, I can't imagine all the frustrations a "stupid" person must feel when they can't comprehend things that intelligent people take for granted... "If only I were a little smarter I could realize my problems and form solutions to them."

From my point of view, I'm always saying to myself: "I've realized most of the problems and found solutions to them... now, how can I convince the Stupids to accept real logic and reasoning?"

Or, on my worse days, it's "If only I were a little dumber then I'd fit in with the majority of people, I would be accepted and treated as their equal."

People are always telling me "gosh you're so smart" but I become insanely infuriated when they won't accept my ideas. They think that I'm crazy for believing in certain things, only because they're stuck in their old backwards small-minded ways of reasoning.

And the laws... oh, the laws! Created by people to protect the ignorant humans from THEMSELVES. And those of us that are intelligent enough to govern our own rules of ethical conduct, we're being repressed by them. We are their slaves. We want peace and happiness, they want money and control.

I could use my intelligence for so much good, and such evil... I'll just work on playing the Apathy card and be an anonymous supplier of healing herb.

Let the world bring about it's own death, as it has done since the beginning of time.
