Well here is the last two. I hope my comments helped you. Writing is always a learning process.
9.) Trust Your Editors: As an editor of a small press I agree. We work hard to make your book as good as it can be. I’ve been lucky enough to have a few authors win or final in contests with the books I edited. That lets me know I’m doing my job. I will put an author be aware on this. When you hire an editor for self-publishing be sure to do your homework. See who else they have edited. Make sure they are a good fit for you.
10.) There are no Certainties: This is so true. You could right the next Pulitzer and not be able to get a publisher to buy it. And as sad as this is you could write a ton of books, but not make what you thought you would and decide not to write anymore. I’ve heard some authors are making this decision. It breaks my heart. We all know writing is subjective. Someone will love your book no matter how many flaws and others will nit-pick every little detail.
