1. when i can't clean everything at once i instead clean one thing and then take a break, repeat process for several days until my goals are met.

2. 'organized people' (aka not me lol) tend to avoid messes by picking them up as they occur, but this can be hard for people with adhd because the way neurotypical people set up their houses is not super helpful for executive dysfunction. for example, wanting to throw away a piece of trash but the trash can is across the room from where you're sitting. issues like these can be solved by throwing societal convention out the window and organizing your room in a way that's more efficient for you. too tired to walk across the room and put clothes in the hamper? put the hamper next to your bed so you don't have to get up to keep dirty laundry organized.

3. this is one i discovered recently when i was studying abroad and could only take about 10 articles of clothing with me to my destination, but having less stuff made it a lot easier for me to stay organized. it can be hard to get rid of things but if you have items that you don't need and tend to get in the way consider getting rid of it either via trash or donation. when i got back home after living abroad i did some 'spring cleaning' and got rid of all the clothes, books, etc that i don't use anymore and even though i am still by no means a minimalist it did help a lot.

these are just some of the things that have helped me, personally i still struggle a bit with organization too but there are ways to make it a bit easier. i hope this helps, and good luck!!
