Would you rather be a worried genius or a joyful simpleton?
I think the phrase, "ignorance is bliss," exists for a reason. The thing about stupidity is that, those that are afflicted with it just don't care. They don't realize they're stupid. People who aren't ignorant are the ones who shoulder the burden and have to deal with stupidity, some more than others. But I'd much rather be the joyful simpleton than the worried genius. I don't like to worry, it's a pointless exercise.
