It’s not that they don’t care.
It’s that they know which validations are worth having and which ones are really badges of shame in disguise.
Dumb people don’t have this knowledge and waste a lot of time on flash-in-the-pan pseudo-validations.
Whales don’t breathe as often as rabbits, but they need air just as much.
Similarly, deeply intelligent people don’t need constant reassurances from others, but they have just as much of a need for recognition and companionship as your average three year old—except that the validations and companionship they seek are not recognized as such by the rabble.
But no, no—there is no longing like the longing of the loner.
