Sorry I left a reply that left you super stressed @superstressy - life got in the way.
I think it's probably worth looking at it the way the autistic spectrum works.
It's not linear, " high functioning" at one end, and "low" at the other. If you look at the photo of the sound mixer I've attached, you see all the sliders at the bottom? Imagine each one is a different strength.
Everyone has a different mixture. No person has all the sliders pushed way to the top, or to the bottom. Neuro chemicals don't behave like that.
Therefore, you can have ADHD, where you're distractable, and feel you couldn't organise a piss up in a brewery, but if it's your own amazing idea, you could find hyper focus kicking in, taking you through an 18 hour day getting all the details right.
You may have the ability to frequently have amazing ideas, but you also have just the right amounts of dopamine, and maybe serotonin to pace yourself, keep a decent process going, but not to the point whe your brain fries.
Then, you may have issues with mental health, such as anxiety, which means that despite having good ideas, the constant effort of trying to "appear normal", keep your more diverse traits in check, means that you find life just utterly exhausting. Which is a shit position to be in.
If you grow up in a house where your abilities are supported, whatever they may be, you are more likely to feel confident following your dreams, whether in a plodding fashion, or with a comet- like speed that crashes into the world one Tuesday. Either is a mixture of self- belief, intelligence, and your own strengths.
But without the right chemicals to manage your behaviour, they will stay in the dreams box, collecting dust, or crash early every time with a lack of planning, insight, and consistent application.
Sorry, bit waffley. ADD, and tired. Bad combination
