Not in a Monk-like fashion, but I have my little obsessions
-For example, when I'm about to go somewhere, I usually pick some tissues, because I use them a lot. And I always have to rub my nostrils with the last one I pick.
-Also, I have to close every FF tab with clicking the wheel.
-When I have a pen in my hand, I have to bite it. It also helps me, because I usually carry three, and I can recognize the one -I'm using because it's the biten, while the others are mint.
-I have to turn off my cellphone when I go to sleep. If I'm in bed and realize I left my cell on, I go turn it off.
-All the open windows in my PC (except the small ones) have to be fully maximized, I get mad when a big one is missing a centimeter to be maximized. This happens usually with Firefox, I get mad when it doesn't start Full-Screen
I probably have more, if I think some others I'll post them
