13. You Write Every Day
You have made a daily practice of writing and are very self-disciplined.
14. Peers
You have one or more trusted readers who will give you feedback and critique your work along the way. Another set of eyes, connected to someone else’s brain, can help you out of writing jams, blocks, and other writerly mishaps.
15. You Know Your Niche
You have defined your niche market, which is another way to say that you have a clear audience in mind. If you account for an audience while in the process of writing, you’ll end up poised to sell the book to them.
