Not diagnosed with anything but struggle with executive functioning.
I have a thing where I challenge myself to do five small cleaning things any time I get up, usually when I’m doing something that has a lot of little natural stopping points where I usually take a break anyway (eg, moving to next chapter in book or completing a level.)
The small cleaning things can be throwing away a piece of trash, finding one thing to attack with a wet wipe, putting away one laundry item, etc. Anything that’s easy to put in discrete chunks. I don’t have a dishwasher so it is sometimes even just wash one dish.
The good thing is that I don’t feel bad when I go back to my game or book, and sometimes I keep going after I’ve met my quota of five things.
I also bought some wooden dice from the dollar store, and I’ll write some tasks that almost always need to be done on them. This helps when I am so overwhelmed that I can’t decide on doing laundry or dishes. I can roll to find something to focus on.
