My current mantra is "I get to decide who I am." Identity is incredibly mutable, but we tend to get stuck with baked in early assumptions. It's so easy to think "I'm not good at this" and sort of silently translate that to "I could never be good at this," when not being good at a thing is everybody's natural state.
Of course, most skills are going to be easier for some people to pick up and harder for others, but that's rarely the determining factor; more often it's who's put in the time and effort.
It's so easy to forget that so many of these things are skills, and to assume that people that are good at them just got lucky, which is not only counterproductive to oneself, it's kind of disrespectful towards the others who worked so hard to get good at them.
