I don't have ADD, but I only like to pay attention to the things I like to pay attention to, and things like getting a TV and getting the cable working are beyond me, and so I let such things lapse, sometimes for years. This applies to keeping my apartment clean.
Some ego is involved because I guess one wants to be perceived as a good clown and one puts one's name on the art; but it's so hard to do anything in life, trapped as we are in our bodies, that is purely selfless for others... somehow the self is always involved.
Twitter is so severe, you know? And it's completely for free, it's scattershot, and it's very easy to feel embarrassed. It's hard to be artful with it. It's like a ticker tape. It's not a forum that's worth mastering, you know?
