I've never had a lot of luck with categorizing and allocating either. Which is actually fine, because what category (or, God help us, categorIES) a task fits into is ultimately not a terribly valuable piece of information. It's costly to obtain, in terms of time spent categorizing, but yields no particular insights, other than maybe the frustrating realization that a surprising number of tasks fit plausibly into multiple categories. (Which is as it should be, if you're productive and your life is reasonably well integrated.)<p>The only question your system needs to answer is what to do NEXT. And the only categories as far as I'm concerned are "work" and "home." Keep it simple. Therefore I have a spreadsheet for each. Within each one, here's what I have:<p>I have a list of things that repeat every day, called "dailies." I do those first.<p>Then I have a list of small one-off tasks that can be taken care of relatively quickly. This list is called, inspiringly enough, "uncategorized." I do these right after the dailies.<p>"Uncategorized" is also the default landing place for any new task. Sometimes you just want to write something down without thinking about it much. Next time I go through the list, any tasks that need to be moved to another list, I'll do it then.<p>Finally there's the "projects" list, which consists of bigger tasks with sub-tasks under them, in order, and with deadlines noted, and the whole bit.<p>Using macros, key bindings and event triggers I can re-order all these lists with one keystroke. Each item has an integer next to it for sorting. I usually use 0 through 4:<p>0 - waiting for something or someone else<p>1 - doing right now<p>2 - next<p>3 - later<p>4 - tomorrow<p>You'll notice that by doing "dailies" and "uncategorized" first, I'm doiog the opposite of what some advice suggests: I sweat the small stuff first. That's because I'm a night person, so I save the morning hours, when my mind is dull, for small, routine and easy things. By the time I get to my projects list, I'm fully alert and ready for it.<p>But if you're not a night person you could certainly do projects first, then one-offs, then dailies, or something. Also there's nothing stopping me from putting something demanding (that happens to be repetitive) on the "dailies" list for example. Something like studying a new technology for a couple hours a day would go on there. But I would probably tend to postpone it until the evening, i.e. put it in the "dailies" portion of the "home" spreadsheet, and start it when I get home from work. (Or if I'm working at home, start it when I <i>declare</i> that I'm home from work.)<p>By the way (back to "projects"), I try like hell to have only one project active at one time. Unless fucked-with by someone else, I will endeavor to finish each one that I start, before moving on. There are many reasons why focusing resources on fewer projects sequentially (rather than more projects simultaneously) is the best way to do things.<p>Therefore my day consists of, go to work, get a bunch of small ducks in a row, focus on a project for the mid-morning and afternoon, go home, do daily chores or studying, get small home-ducks in a row (things like "order underwear" or whatnot), and if there's time (usually not until the weekend) work on a home-project. I like sleep.<p>Things that recur at intervals other than a day, those go in the calendar, and I get a reminder, every n months or n weeks or whatever. From there I use automation to transfer it into the "uncategorized" area. (Home or work, depending on whether it came from my home or work calendar.)<p>If I ever think up a big over-arching life goal, I will make it a project or split it up into projects. Projects are things that you do. Goals are things you just think about, that I don't really believe in. Or rather, if it's important enough as a goal, I don't need to write it down, I just let it influence all my decisions in that direction. It's best not to have too many goals; just a few high-quality ones. Kind of like how it's best to have just a few high-quality friends. Life is not a shopping expedition; or actually maybe it is, but I say that as someone who thinks the fewer things you "buy" (into), the better. Also it's not good to try to plan out your entire life; give yourself some freedom to steer the ship in real time. Rely a little on your wits and creativity instead of on a script.
