As a person with A.D.D., I cannot live without my list. I have about 5 floating around at all times, and I like to keep a master list in big plain site too.
In my new office I didn't want to add more clutter with a white board. I had a big mirror hanging over my desk and a bunch of whiteboard markers, so I improvised.
Works great, and much prettier than a whiteboard.
The only downside is now whenever I look at the mirror to check my list, I can actually see the overwhelm on my face and that I really need to tweeze the brows- need to add that to the list.
