@calcifer i'm not diagnosed with anything so.. just ignore me if you want.
i use a magnetic whiteboard with rows for each day and magnets with icons on them representing tasks. if you done it, just move it to the next day. it's more "fun" than lists, because it's easy to just put a magnet onto the next day instead of searching a pen etc. i think icons are nice because you don't have to read. the whole thing can be varied a bit, e.g. take the magnet, do the thing and put the magnet back when you are finished. it's kinda kanban :)
