I am a strong believer that the biggest "thing" in ADHD is the challenge with sustained goal-focused behavior. And that is in large part due to how fucking hard it is to stay on task when you have ADHD. It's not uncommon to hear people like you who are able to keep control by focusing on the few things that make the most sense and are the most motivating. And even with a perfect target for behavior, it's a battle to keep at it. That is why I think a lot of people get adult-onset ADHD diagnoses—because they are burned out from spending 2x the energy to keep their life and behavior on track.
