Intelligence is the greatest indicator of an individual's long-term success. It's pretty much the only thing that matters. Modern weaponry leveled the playing field when it comes to physical strength. But speed and accuracy was always a great counter to STR anyways.
Everyone knows at least one thing you don't though; I've received some profound answers to many questions lurking in my mind from normies at times.
After about 120IQ your brain will lean towards a specialty; emotional awareness, pattern recognition, athletic capabilities / body awareness / dance, creativity / intuition, etc. I try to nurture all of the skillsets since they all bolster each other. Movement is excellent for the brain.
I'd say my greatest talent though is being unfathomably annoying. I have a gift for bringing out the worst in people so I know who they are in very little time.
