Dear Eric: I’m a self-published fiction author. I’m really struggling with jealousy and despair. Every time I see a published book or step into a bookstore, I feel this wave of sadness. I’m trying to get my books out there, get whatever reviews I can, and promote myself on social media but it feels impossible. A friend just told me she won’t try out a new author unless they have thousands of good reviews on Amazon or GoodReads.
