Intelligence is not easily quantifiable (dont you dare get me started on IQ) so its pointless to worry about how you stack up in one area. Ive met a genius nurse who cant spell restaurant without spell check. I know engineers who cant visualize a 2D drawing in to 3D space. I think im pretty smart, lots of conceptual thinking comes naturally to me but I hate chess. It doesnt make sense to me. I suggest thinking about what you are good at, rather than what you’re not.
