Whether you’re submitting to literary agents for the first time or preparing to self-publish your book, you probably know the value of hiring an editor. Copyeditors are indispensable in that they not only correct errors, but they also create clarity and consistency; luckily, their changes tend to be easy to incorporate. Content editors, on the other hand, focus on big-picture issues like narrative arc and premise. Are you prepared to rethink such issues—or to have someone suggest that you do this in the first place?

I’m probably the last person who should be writing about investment strategies. Math was never my forte, so I intentionally chose a field in which I could focus on words. As it turns out, I can’t escape numbers: When I worked at a literary agency, we negotiated things like advances, royalty escalators, and sub rights splits for our clients. I did the same for publishing companies, where looking up sales figures and running profit and loss statements were part of my daily tasks.
