Everyone wants to get a diagnosis of ADHD and/or autism so they can spend the rest of their life never growing or improving and living under the pretense that they don't have the ability to do certain things because a professional told them their brain is inherently limited. When in reality these diagnoses are just categorizations of behaviours, not some kind of scientific barrier baked into the coding of the universe.
I think people would be better off not dwelling so much on the "facts" they think they know about their own brains. It's inherently limiting to assume everything your capable of can only come as a result of the function you think your brain operates on.
