Cory Doctorow, freelance writer and novelist, has written a short article on
how to write productively in the age of ubiquitous distraction. The advice he gives is rather novel; he dismisses the usual advice about switching off one's internet connection, and is also scornful of the idea of ceremony, or of setting the right mood. (And understandably so; acknowledging the idea of there being a right mood or atmosphere for evoking one's inner muse could lead to finding excuses, consciously or subconsciously, for not actually doing anything.)
The single worst piece of writing advice I ever got was to stay away from the Internet because it would only waste my time and wouldn't help my writing. This advice was wrong creatively, professionally, artistically, and personally, but I know where the writer who doled it out was coming from. Every now and again, when I see a new website, game, or service, I sense the tug of an attention black hole: a time-sink that is just waiting to fill my every discretionary moment with distraction. As a co-parenting new father who writes at least a book per year, half-a-dozen columns a month, ten or more blog posts a day, plus assorted novellas and stories and speeches, I know just how short time can be and how dangerous distraction is.
Short, regular work schedule. When I'm working on a story or novel, I set a modest daily goal — usually a page or two — and then I meet it every day, doing nothing else while I'm working on it. It's not plausible or desirable to try to get the world to go away for hours at a time, but it's entirely possible to make it all shut up for 20 minutes. Writing a page every day gets me more than a novel per year — do the math — and there's always 20 minutes to be found in a day, no matter what else is going on. Twenty minutes is a short enough interval that it can be claimed from a sleep or meal-break (though this shouldn't become a habit). The secret is to do it every day, weekends included, to keep the momentum going, and to allow your thoughts to wander to your next day's page between sessions. Try to find one or two vivid sensory details to work into the next page, or a bon mot, so that you've already got some material when you sit down at the keyboard.
Leave yourself a rough edge.
When you hit your daily word-goal, stop. Stop even if you're in the middle of a sentence. Especially if you're in the middle of a sentence. That way, when you sit down at the keyboard the next day, your first five or ten words are already ordained, so that you get a little push before you begin your work. Knitters leave a bit of yarn sticking out of the day's knitting so they know where to pick up the next day — they call it the "hint." Potters leave a rough edge on the wet clay before they wrap it in plastic for the night — it's hard to build on a smooth edge.
Realtime communications tools are deadly. The biggest impediment to concentration is your computer's ecosystem of interruption technologies: IM, email alerts, RSS alerts, Skype rings, etc. Anything that requires you to wait for a response, even subconsciously, occupies your attention. Anything that leaps up on your screen to announce something new, occupies your attention. The more you can train your friends and family to use email, message boards, and similar technologies that allow you to save up your conversation for planned sessions instead of demanding your attention right now helps you carve out your 20 minutes. By all means, schedule a chat — voice, text, or video — when it's needed, but leaving your IM running is like sitting down to work after hanging a giant "DISTRACT ME" sign over your desk, one that shines brightly enough to be seen by the entire world.
I wish I only had to work 20 minutes a day...
