As a child, I was run through a system that seemed extremely concerned that I was mentally deficient and incapable. As an adult, since hitting certain kinds of prominence, I've had a lot of people try to convince me that I'm a genius.
I shoot it down also because I fear that some day I might believe it, and I will also become an insufferable asshole, just like everyone else who thinks they're a genius
But I also know well enough, it's stubborn enthusiasm, privileged access, luck, not "genius"
