A boy, if he's lucky, discovers his limitations across a leisurely passage of years, with a self-awareness arriving slowly. That way, at least he has plenty of time to heroically imagine himself first. Most boys unfold in this natural, measured way, growing up with at least one adult on the scene who can convincingly fake being all-powerful, omniscient, and unfailingly protective for a kid's first decade or so, providing an invaluable canopy of reachable stars and monsters that are comfortably make-believe.
