Yeah, I think there are some people that can pick up on certain things much faster than the average person. However, I'd say the average person can get to be pretty good at most things with a fair amount of practice. And of course there are some things that a given person will struggle with no matter what level of effort.
But most people, most things, you can gain a reasonable proficiency if you put in the time and mental focus.
Completely agree with all of this.
