The story of how Higgs predicted his mechanism was part of what got me into physics as a kid. It fit 10 year old me's obsession with the 'soft-spoken genius' archetype perfectly and formed a pillar in my belief that 'genius' was made through hard work (and some amount of luck) rather than being born with it. The announcement of the detection at the LHC is a core memory of mine, I still distinctly remember where I was…
What makes you think he wasn't born with it? I can see in own kids that each one is built differently, with different inmate propensities despite similar environment.
While all of us have things we find easier to do than the average person, short of a literal mental disability, we can build up skills in things we are not good at through practice. I used to barely pass in math class and didn't even understand the concept of negative numbers until 8th grade. A year of practicing daily for 2 hours after school, and my fundamentals had gotten good enough that I unknowingly derived a calculus-based solution to some problems I was stuck at, 2 grade levels before when I'd actually start learning calculus and got to skip a year as a result.
Similarly, I've been teaching myself to draw despite having been pretty terrible at it and discovering how 'deliberate' most professional artists have to be with practice and building skills.
I think it's pretty common for people to write off their inability to do something as just a lack of innate ability, when it's really just that no one really sees the struggle anyone famous for their work/skill has gone through to get there.
