I didn't say it's easy but if you make the effort to put something in a consistent place, it will be there later. Some things are that simple, you just have to frame them that way and be proactive.

I used to lose sunglasses monthly, lost my wallet more times than I can count as an adult, missed appointments, constantly had to "go back" for something I'd forgotten or left behind. Constantly.

I have to be more pro-active than other people but I realize I'm just going to get downvoted more for suggesting that ADHD and symptoms are manageable and have workarounds.
