then everybody is of equal talent and should pick things up at an equal rate as a kid and therefore should be, bar minor variations, equally talented.
Fact is they aren't, because people are naturally better at some things than others, and they then develop that skill.
Messi could have had my left leg at aged 5/6, played on the streets of Argentina and you know what? he'd still be there.
No, because your environment from the first second that you are born determines this. Messi's a better footballer than you because he played football more than you did, and learned how to use his short frame in a beneficial way. Hell, if Messi was English, he'd be SWP.
People are smarter than others because they focus on mentally challenging activities more than others during their development stages, which leads into a mental framework which is used to adapting information. Look up Piaget's theory of Cognitive Development; I actually did my dissertation on this.
