In primary school, I remember a kind of status indicator being the memorisation of song lyrics (at our age, mostly that meant Vanilla Ice and MC Hammer, if I recall). I placed great importance at that time on my memorisation abilities, and now I wonder if I have ever really grown out of that. I attend trivia competitions regularly, though my knowledge is narrow rather than broad. I still take pains to learn song lyrics, not just to be able to sing along, but to be able to impress people by singing along. The urge still happens to me to this day. So I'm really not sure I ever grew out of that need for external validation, and that idea that having an impressive memory is the way to get it.

PS - I wish I didn't need external validation to feel good about myself.
PPS - It would simplify my life enormously.
