I changed to third person. Yes, writing books is hard, but it should not make you want to throw things or hit people. You should not have to dread every. single. minute. of your writing time. Writing, although it is hard and can be frustrating, it should also be fun and exciting.
Now that I've changed to third person I feel like writing more in the series. I was literally ready to stop at book 3. I only planned four in the series, but left it open enough that I could add more later. But now I'm thinking it's been opened up to write more books...all from switching from first person to third person.
I am debating on going back and updating books 1 and 2 into third person. That would be complete rewrites and a massive under taking, so I'll hold off for awhile.
If you're ready to dig in, you can purchase the book at Amazon. It's also available on Kindle Unlimited. Click this link.
