1. Clean up your manuscript
Go through and look for idiosyncrasies and inconsistencies. For example, I know I’m a huge fan of starting sentences with conjunctions (and, but, so, yet) and I have an over abundance of phrases in parenthesis. These are my personal writing idiosyncrasies. I don’t want to get rid of them all, but I make sure that each use either furthers the writing or is needed to keep the writing in my “voice”.
I also clean up any inconsistencies. For example, in the cookbook I’m currently editing I find that I’ve used the following:
That’s four different ways to say the same thing! I decided on one standard format and will be keeping it the same throughout the book. (And using the same format for cup, pound, and teaspoon!)
When I edit for clients, this is one of the main areas in which I focus. I don’t really care if you want to say fig. or figure but I want it to be the same throughout the book!
