I have often been asked by authors, "When should I send you my manuscript for an edit?" Sometimes they have just finished writing, and sometimes they are still in the process of writing. Some have already done some self-editing and beta reading, and so they know how important this process is already. But for those new to the writing process, here are some important tips for doing your self-edit before submitting to your editor. Because if your editor has to focus on all the little things, you're not getting the other, more in-depth valuable feedback s/he can offer you. And I'm sure you want to spend your money in the best way possible, right? :)
