I've seen a few people use various reminder methods for ADHD and other executive dysfunction/memory issues, and I've used many myself, but as of yesterday I'm trying this method where I have key tags labelled with various tasks attached to carabiners and then I wear the one with the ones I need to do today on myself around the house and it rattles and reminds me stuff needs doing, it worked great yesterday and I'm hoping to keep using it!
The green carabiner is today's task, red is storage for things I don't need to do and the gold one is completed tasks!
I have some labelled Task A, Task B, etc which are for one off rather than regular tasks (which are written on my to do list), and all the others are labelled with specific daily or regular tasks!
