i find this stuff mildly amusing. i admire "planners", and wish i was one.
for me, aside from concert tickets, plane tickets and the like, i plan most things inside of a 10 day window. and maybe for holidays, add a couple weeks to that. yes, i frustrate some people, but it sort of goes against my nature to be "locked in for stuff" if i can wait as long as possible before someone's plans are dependent upon me.
of course, there are exceptions to this rule, but they tend to be things that i already know i will want to do, such as things i hugely enjoy.
i am not really a holiday person. while i'm especially sensitive to the sentiment behind christmas and find it to be a very meaningful time of year, the fact that it locks up the whole month (or more), creates scheduling nightmares for work, am forced to hear 7 weeks of christmas music blaring everywhere i go, non-stop advertisements and commercials, and people blathering on about their holiday shopping provide all sorts of compelling reason to want to go spend this year's holiday somewhere super-remote, where i wait it out in the beautiful distraction of someplace where they don't pipe christmas music in and have throngs of rude people talking about the "christmas spirit". i dunno where that might be, but i'm prepared to sleep on an airmattress and live on peanut butter and protein shakes to do it.
....so no, i have no plans. : )
