On Merlin Mann's 43 Folders productivity blog, he runs through a great high-level overview of the geek-cult-smash, "Getting Things Done," a comprehensive and nerdy guide to systematizing yourself out of procrastination.
Stuff is bouncing around in our heads and causing untold stress and anxiety. Evaluation meetings, bar mitzvahs, empty rolls of toilet paper, broken lawn mowers, college applications, your big gut, tooth decay, dirty underwear and imminent jury duty all compete for prime attention in our poor, addled brains. Stuff has no "home" and, consequently, no place to go, so it just keeps rattling around.
Worst off, we're too neurotic to stop thinking about it, and we certainly don't have time to actually do everything in one day. Jeez Louise, what the hell am I, Superman?
So you sprint from fire to fire, praying you haven't forgotten anything, sapped of anything like creativity or even the basic human flexibility to adapt your own schedule to the needs of your friends, your family or yourself. Your "stuff" has taken over your brain like a virus now, dragging down every process it touches and rendering you spent and virtually useless. Sound familiar?
