I have to admit it. There are several things I loathe in life. Beets, yellow mustard, folding clothes and editing. Oh, there are other things on the list, but I am the most passionate about these four. And the number one hate on the list is editing.
Okay, maybe that is a bit extreme, but I think you get the picture. The editing process doesn't just make your book/story/novel/etc. better; it makes you better. And therefore it improves everything else you write. I have written eight books and on each one I employ the same editing "suggestions" given to me on my first book. And my second, and third, and so on.
As I write now, I notice that the editing "suggestions" I was taught (and I had some amazing editors!), are now things I use almost without thinking. And I don't even use italics with them anymore. And even better, I use them when I make "suggestions" (ahem) to my indie author friends who ask my advice about the publishing world. Imagine that. Hmmm.
And that's important, because guess what? As humans, editors talk to other editors and the last thing you need on your impossibly gut-wrenching journey to greatness is to piss an editor off. You don't want to be known as THAT WRITER. At least not for piss-poor critique accepting. You want to be remembered for being THAT WRITER of the amazing novels. And so will your editor. Good luck.
