Writing takes diligence. The writer who fools himself (or herself) into thinking it doesn't is the writer who always dreams of being a writer—but they never quite get there. Being a writer isn't about getting published (although the extra pocket money is nice, of course). You are a writer if you write—which means all those dreamers out there who have been sitting on that book idea, hoping it will someday be a bestseller, you had betterget up off the couch and park yourself at the computer desk.
The best way to do this, and one that author L. K. Below uses in her outrageous Book-a-month resolution, is to set goals for yourself. Personally, I can't do a book a month—I doubt many can. However, a smarter goal which you know you can meet might be appropriate. Maybe to finish a chapter a week, or a short story a week. When you set yourself goals like that, you push yourself to write. And the more you write, the more that will be available to be published. It's a very lucrative circle.
So then why are you still sitting there, reading this blog? Get writing!
