But that's not really any different from how people vary from one another in general. It just so happens that the way in which I vary is shared with many others and has a name.
I'd say the same about ADHD. I don't know if I have ADHD, specifically, but I certainly have some form of related executive dysfunction. It makes it very hard to focus on something tedious (I spent a solid hour trying to type up a few paragraphs of interview feedback for someone earlier while getting constantly pulled off onto other things). But it also means I temperamentally have to constantly be learning and growing because I'll wither and die if I don't. That has made some things (like doing repetitive daily tasks) hard, but it makes other things (like the fact that as a founder I have to do about seven different jobs at a time) fun and easy when they would crush many people.
I agree with you that we don't need to pretend that things that hurt us don't. The difficulties matter, in part because acknowledging and understanding them is a part of finding our own personal brands of excellence. But I also don't think we need to treat the ways in which we're different as a curse, either. It's just how we are, and we have to figure out the best way to live within those constraints, the same as anyone else. Sometimes that means tolerating the things that we can't change, sometimes that means routing around them, sometimes that means figuring out ways to make them work in our favor.
I can't speak for everyone, but I can say that my life has gone far better starting from the premise of "this is the way I am and I have to work with that while recognizing the realities of interacting with a world that operates on different rules from mine" than it has from the premise of "I'm broken and I need to fix myself so I'm like others". In that sense, I think that acceptance, and even celebration in the right ways, can be good. It's just a way to say "it's not wrong to be what you are, and you should try to be the best version of that thing, not the best version of someone else".
