After I've sent my revised draft to my agent and editor, they suggest more improvement sand again, this revision phase can take anywhere from a few hours to a few months.
Eventually the bad stuff I'm writing turns into better stuff. Other times, I've just walked away from what I was working on, and figured I'd have a better perspective when I came back to it.
Generally I finish a first draft in 2-6 months, then I set it aside for a while so that when I come back to it I can read it with fresh eyes and figure out how to improve it.
I loved to read when I was a kid, and as soon as I realized that an actual person got to make up the books I loved so much, I decided that that was the job for me.
I write a book over a period of months or years, and when I'm done with it, usually another year goes by before I see it in print. It's hard to be patient and wait.
It's just so much fun to make up characters, situations, and everything else about a story. I have so much freedom and flexibility to do whatever I want.
The deadlines are much, much longer with books. When I was a reporter, a lot of times I'd come in at 8:30 a.m., get an assignment right away, interview somebody, turn the story in by 9:30, and have the finished story in the paper that landed on my desk by noon.
When writing isn't going well-then the bad thing about being a writer is that I also have the freedom and flexibility to do something badly, and no one else can fix it for me.
