That's an awfully high "minimum". I knew several "geniuses" at that age (might even qualify myself, though admittedly I was only three years ahead of par at that age); most of them have gone on to fairly normal (though by no means unsuccessful) careers, and a couple burned out quite spectacularly. I don't think putting that weight of expectation on is helpful.
