How fucking hard it is to remember daily and recurring tasks. Taking meds, brushing teeth, checking email, cleaning up, cooking, laundry, on top of stuff related to work.
Another one is that we are blind. Unless I expect to see it, I cannot see it. I literally dont see clutter. Only when I force myself to think about what I'm staring at do I realize there is a bunch of crap on a table. Its really easy for my room to get messy because of this. Because it hardly exists for me.
