I have no problem with wanting to put effort into things despite drudgery or difficulty. My main problem tends to be that I sit down to do something, or think about how to do something, and a thought pops into my head that's tangentially related. I follow that thought, usually involving a Google search, and it leads to a third thought, then a fourth, and the next thing I know I've spent an hour Not doing what I'm trying to do. So I refocus, try thinking about what I'm trying to do and how to solve it, maybe make a bit of progress, another thought pops in, etc. I like to call this my Internal Distraction Loop.
This feels especially jarring when it's so easy to enter a hyperfocus/flow state and tackle a task for 4 hours straight on some tasks but on others I'm _constantly_ trying to pull myself back on track every 30m or so.
It's doubly frustrating when it's the Same Task, where I've made a ton of progress one day, and the next day I get caught in a distraction loop.
It's triply frustrating when it's something that I know should only take 30m tops if I could Just Focus but ends up taking me hours and hours.
Quadruply frustrating when that expectation of "oh it'll take me forever" turns out to only actually take like 15m (and for some reason my expectations rarely adjust) but I'm digressing a bit.
Sure they're problems everyone deals with, and everyone finds a way to deal with it. But some people find it More Difficult to deal with. I find medication to help when it comes to controlling my attention. Or copious amounts of coffee.
Sometimes it helps cut down on how frequently I enter my core distraction loop, or it helps me notice the loop earlier so I can abort.
Anyways, yes executive function is a skill everyone has to learn at some point in their life; these are problems Everybody encounters. But it's Harder for some people, the same way learning to read is harder for someone who's dyslexic or public speaking is harder for someone with a stutter.
And executive functioning disorders are frustratingly self-perpetuating; how do you put more effort into focusing/putting more effort into things if you have trouble Choosing to put more effort into things in the first place? It's recursive. Medication helps break the loop (but is often over prescribed or misdiagnosed, and imo should be a scarce or temporary measure; a crutch to help develop the right skills to fill one's executive functioning gaps, but that's a different discussion).
