It isn't just laundry of course. This meme speaks to motivation as other folks commented.

Motivation can come from emotion either from response to external input or ones own thinking.

Motivation can also come from the brain's executive function, where you decide to "Just do it".

So if someone yells angrily at me to do a thing, or if I am freaking because the deadline is early upon me, or there is an emergency, or if a friend asks for help, the emotions can motivate me easily as is the case for anyone.

If I know I need to work on a boring thing today to save myself from panic later, the "just do it" part of my brain doesn't have enough oomph to actually get me to do the thing. Like, no amount of pushing myself, self goading, self talk, nothing. It's like trying to push a car alone with the parking brake on. I just can't budge myself.

When I am on medication, it can still be hard but I actually feel like getting something done, I want to do it, and I am able to just will myself to do the thing. I can just be like "yeah this sucks, it's boring but fuck it let's do this" and then, unlike before, I actually start doing it. Which is still a marvel to me even though I have been on meds for several years. I don't think most people find self motivation to be a novel thing to marvel over. I think most people are more able to convince themselves to do the sucky boring thing if they just set their mind to it. Being able to do that (even if difficult) is taken for granted.

Which is why ADHD people are told they are lazy or told to "just do it already". Normal people don't know what it is like to have a broken "just do it cortex" :)

One of Dr. Barkley's videos explain the motivation issue really well.

And the thing with ADHD is that it is a constant, every minute of every day struggle with motivation if your line of work involves too little excitement and a lot of tedious boring stuff.

It was bad enough with me that the only way to function even close to average was to be in constant fear and panic about forgetting things, missing deadlines, getting in (more) trouble, while failing to avoid those things constantly and gaining a reputation as an unreliable lazy flake, eroding trust, and performing poorly in work, school, in relationships. The result was getting lower grades than I could have without ADHD as well as missing out on career growth, losing friends, etc.
