How the heck did you convince yourself to believe it? As a "gifted" kid, what I learned very quickly was that adults will happily exaggerate minor talents (which one acquires primarily through just spending time on them, a task made markedly easier when everybody else hates you) to absurdity- at one point I got an evaluation back from a summer program at Stanford telling me I might grow up to be "one of the best programmers of our age". What did I do to earn such acclaim? Got ahead of the rest of the class making a game, read the documentation for Flash, and used the extra time to add "voice controls" to my game (specifically, you'd shoot by yelling anything into your microphone, it was just triggered by levels.)
Seriously- how can you take that sort of praise seriously, and not just as a "look at the cute kid who knows more Adobe Flash than the rest of his age group"?
