I imagine it like this (good idea coz also autist): Normal people have more or less steady levels of concentration, focus, etc. ADHD people have it a lot different:

low activity mode
medium activity mode
super-high activity mode

but I also think, that in the end the total activity expense has to be equal of a normal people so it's all about compromises: think less for 5 days, then brainstorm for 3-6 hours 1 day and achieve concentration and capability levels that normal people can only dream of.

the problem is knowing which mode is when, and if it's possible to influence them? for example today I got my super high activity mode triggered by A LOT of sugar. Right now I'm doing tasks that required my mind to "JUMP" high, and for a long time far away. I'm doing it.

but also fuck had also something important to say - forgot.

I'm doing like 3-5 things "at once" - I mean in 1 query - pausing the doing the other thing, rinse and repeat.

alright, I backtraced my own thoughts ( going backwards thought by thought ), I remembered:

It actually does feel like 3 modes (again but different comparisson):

normal car, sometimes
super shit car what the fuck super slow, sometimes (but also, in this mode we can do things and act as we usually do - the muscle memory for example can automatically jump in, or other things such as doing things we used to - just repeating, but sadly a lot of the time that doesn't work, and being in this mode while at a workplace, and ESPECIALLY if you're new to the company or whatever... it's a very bad timing)
600 hp muscle car, sometimes

compared to normal brains (neurotypical):

normal car, sometimes
a bit slower car, sometimes
200hp better car, sometimes
