When I was working, I used to be very "Type A" and although I was always early for appointments, I didn't give myself room to breathe between them. I craved deadlines, because most of my work was done during one week of the month, and (great for me) it was a steady do-it-by-deadline format, to which I thrived.
Since I haven't worked since 2006, many things about me have changed (still Type A, but better than I was), including the need to schedule. I will overthink and obsess on something for weeks, but when the day comes that I have to act, I can get it done. For instance, if I need to change a doctor's appointment, I'll think of it for a month, but not act until I'm just short of the 24-hour deadline. The weird thing for me, though, is that I keep a calendar in my head, so they stuff I "have" to do, always seems to get done.
While I've always considered myself completely spontaneous in my personal life, I've realized lately that even my spontaniety (sp?) is planned. I have things laid out "just in case" I have to go somewhere, or I'll walk to the laundromat and wash a half a load of laundry, just to get out of the house.
I have been getting lost lately (which is good, in a way) so I've had to navigate in my head where I am, but as far as schedules/rituals, I'm not necessarily busy enough to have them. I worked on contract with a guy who spent 5-6 hours a day writing lists of what to do, and then expected me to finish everything he wrote down -- in the next two hours. That didn't work with me. I also used to hang a "To Do" list on my wall, and he would try to add things to it. I stopped him and told him that was MY list, not his.
One of the reasons I've never joined a Book Club is because I can't read "on deadline." It caused problems in school, considering I could read a book I chose overnight, but if it was on deadline, I'd read the first chapter and the last page (smile).
