For hobbies/projects or just general upkeep, I find it helps to have dedicated, visible places for things. Myself and my wife both have ADHD, so we’re a bit of a mess lol. My wife likes to paint and she has a dedicated table and cart that contains all of her art stuff. In theory, it stays there and never leaves. She’ll occasionally take things out of their space and they will be forgotten/abandoned for weeks. When it stays in its place shes more active and doesn’t quit on pieces due to not having easy access.

I like to cook and find the same to be true in the kitchen. Certain things go in certain drawers, cabinets, etc. Obsessively. They have to be exactly where they’re supposed to be or I’ll either forget about them or try to improvise, often with not great results. So I guess my advice is to keep things where you’re most likely to use/need them and do your best to stick to it. Having multiples of whatever your “thing” is also helps. Within reason of course. There’s no need to have multiple drills, stud finders, blenders, etc.
