Writers are full of excuses. It's the day job or the kids or the telemarketers that keep them from finishing that article or working on their novel. In reality, the main distraction we writers have is ourselves. We allow ourselves to get put off track by the annoying boss or the nagging telephone. We don't put in any work after the kids are in bed. Whatever the distraction is, it's the writer who is letting it be a distraction in the first place.
My big distraction is the Internet in general and email in particular. As soon as I rev up my old laptop in the morning, I check my email. I read any editors' messages first, then trawl through the newsgroups. Then I check the news. Then I surf a bit. Then I check my email again. By the time I'm done, I've lost the initial surge of energy I always have in the morning.
That's why from now on I won't connect my router until I've written a thousand words every morning. That sounds like a lot, but if you focus it really isn't all that difficult. I don't want to be one of those writers who is obsessed with word counts, because quality does count over quantity, but to get the job done you do have to produce a fairly large amount of writing. I make myself write a minimum of 7,000 words a week, although I try to shoot for 10,000. Cutting myself off from the Internet during my most productive period of the day might push that higher.
All writers have their own techniques, but one common thread is hard work. Writers don't get to just laze around drinking wine and have great books appear out of nowhere. Even Kerouac put in long hours. Victor Hugo used to wake up at six every morning and write uninterrupted until two in the afternoon. It's the only way he could have finished a tome like Les Miserables and done all that journalism on the side.
Besides, all those editors can wait. They usually take weeks or even months to reply to my pitches, so waiting a few hours won't kill them.
