The people at the top of any competitive field are not only well trained, they are also well suited to the task. And this is why, if you want to be truly great, selecting the right place to focus is crucial. In short: genes do not determine your destiny. They determine your areas of opportunity. As physician Gabor Mate notes, “Genes can predispose, but they don’t predetermine.” The areas where you are genetically predisposed to success are the areas where habits are more likely to be satisfying. The key is to direct your effort toward areas that both excite you and match your natural skills, to align your ambition with your ability.
