I'm a sloppy writer who usually discovers the story along the way. Early drafts lack focus and contain more bad writing than good. Luckily for me, I know my future drafts will get better. There's controversy about how much revision is warranted in any given piece. I would agree that revising means the writer sees a lower hourly rate, except that I would have no hourly pay without revising.
Some professionals swear revision is a waste of time.
Publish without revising if you can, but if your work does not consistently receive the attention you know it deserves, consider learning to revise. Approach the process as you would a math problem. The only concepts to remember are Addition, Subtraction, and Fiddling With the Equation. When revising your work, there are things you might need to add or things you might need to take away. When neither concept helps, change the overall structure.
