The most important thing is habit, not will. If you feel you need will to get to the keyboard, you are in the wrong business. All that energy will leave nothing to work with. You have to make it like brushing your teeth, mundane, regular, boring even. It’s not a thing of effort, of want, of steely, heroic determination. (I wonder who pushed the meme that writing is heroic; it must have been a writer, trying to get laid.) You have to do it numbly, as you brush your teeth. No theater, no drama, no sacrifice, no “It is a far far better thing I do” crap. You do it because it’s time. If you are ordering yourself, burning ergs, issuing sweat, breathing raggedly through nasal channels that feel like Navajo pottery, you’re doing something wrong. Ever consider law? We definitely need more lawyers.
