Problem: Could training possibly help a person reach some level of competency in this area, with that level depending upon some qualities specifically found in that person? Might a trained level of competency still "lag" behind the level of "drive" found in a person who apparently was born that way? If you thought people needed to be born with "drive" or instead you thought it was a trainable attribute, could there still be a discernable difference in performance between the two types of individuals?
