what is your most compulsive habit?

Um...I find it hard NOT to be busy. I guess this is compulsive, because I don't realize I'm doing this most of the time. Yeah...I'm a workaholic.

I'm not really compulsive about anything, but I do like to sit in my usual table at the coffee shop. I have a place that I like to work because the lighting is good, and it's private, not to mention it's near an electrical outlet, so when I come here I like to try and get the same chair every time.
