Burnout is actually why I don't have anything published. Book 1 is done, but it's a very open ending that would likely get me lynched. So I am working on book two now. Because if I don't write well I have the motivation to, who knows when I'll drop it and for how long, and I don't want to do that to the readers.
I stop reading and writing fanfiction in my free time when I feel overwhelmed. Instead, I started exercising and sleeping more, and in a few weeks, I can write again!
