Except for the fact that Gene Roddenberry was never a comodore commodore for Starfleet Command, this is a fairly authentic ID card, yes? And yes, I did wear a Captain Kirk shirt to school on picture day. I lived (happily) in a world of my own imagination, something I've discovered recently I still do.
As far as realistic childhood goals are concerned, my next major one was to be one of the Beatles. Based on that picture, I already had the hair for it.
