Successfully managing ADHD means throwing the empty shampoo bottle towards the bathroom door so you'll see it when you walk out and then write "Shampoo" on the chalkboard hung up next to your front door where you'll see it before you go shopping so you can put it on the shopping list on your phone.
Seriously my adhd management system is basically "putting shit where I'll trip over it" and then waiting to get sick of still deliberately stepping over/around the inconveniently placed item.
it's this, or recognizing that you don't actually need shampoo and can just buy a life supply of soap bars all at once and use that for washing every part of your body.
i've come to recognize that a big part of why i find minimalism so nice is because it brings the amount of things i need to remember down to something vaguely manageable.
I've been honing my ability to add things I need to a list on my phone's home page. I've been doing it for 7+ years now. If someone asks 3 years later, how much butter to use for belgian waffles that I made once, I'll know it is the blue colored note, 5th line from top.
If I go to the store, I'll still forget I have the list.
Sometimes when I have a great idea but am in bed and about to fall asleep, and don’t want to take out my phone and wake myself up, I’ll grab something off of my nightstand and yeet it into the middle of the floor with the idea in my head, so the next morning I’ll wake up and see the thing and remember my idea… works surprisingly well!
Idk about ADHD but I buy a bunch of shampoo and conditioner, and when I notice I'm at the second-to-last bottle I put it on the shopping list on Google keep
I've got a Google mini in the bathroom so I can listen to a podcast while I shower. The side benefit to this is I can yell out to get it to add shampoo to the grocery list
