Consider " The Summer of '42 "
I'm not saying that a million thoughts per second don't course through the mind of a 13-year-old boy. We were all that age once, and we know.
I'm suggesting that, unless it's necessary as a milestone in the development of the protagonist (e.g., adolescence as the awakening of both his adulthood and his psychic powers), or as insight into the waitress who will later trigger a crucial decision point in the story (e.g., when bad Dad murders her it coalesces the hero's understanding of morality and rejection of apathy toward evil), it's a bit creepy.
Note bolding above. It may very well be necessary, in which case run with it. And use it as the cover art! It will undoubtedly boost sales.
