Of course. I agree with you. You will only make it in that field if there’s literally nothing else you can imagine doing.

But there’s still a starting point and ceiling in intrinsic ability.

I’m curious why you think there’s no difference in inherent abilities? Some people are more “naturally” skilled at some things than others, at a baseline. You can look to see examples of this everywhere.

That doesn’t negate the dedication/sweat/tears of people who have high skill, but many of those people also started several miles ahead.
