This month's interviewee is Jon Karp from Twelve.
My advice to writers would be to aggressively seek the truth—forget about your ego—and do one more draft than your agent asks you to. The writers who I have noticed being successful are the ones who are making their agents wait for that next draft. It's the authors who don't pursue that next project until they're sure it's the right one for them. It's the ones who turn down the easy overture from the publisher for the quickie book and wait to do the book that they can really commit to.
