Read your book: This may seem like an odd piece of advice, but it is important to read all the way through your manuscript before sending it to your editor. Once you can read through your book without making any changes, then you can send it to your editor.
Know what you are paying for: You and your editor should discuss what the price you are paying entails to prevent disagreements throughout the editing process. Hopefully, your editor will have a contract that states all the details, but if not, make sure you have some sort of written agreement on what your editor will do for you.
Keep an open mind: We understand it’s hard to hear that the book you’ve been slaving over isn’t perfect, but it’s important to keep an open mind to suggestions. Your editor is trying to make your book better, so at least consider what they have to say.
Follow these tips and your editor will be happy, which is what every writer should want anyway.
