Being a part of this author community, I know how authors dread reviews. Do you know if it's good? Bad? Maybe somewhere in the middle? Here's my take:
I personally don't read most reviews. A mentor of mine told me once: "It doesn't matter what other people have to say as long as you know what you're going to say." I've always considered that sentiment when publishing something. There are going to be people who love your stuff and there are going to be people who hate your stuff. That's applicable in any situation whenever you have a product to sell.
I've found, people write based on their emotions, which is not always constructively written. I remember in school my professors saying we'd write "critical" reviews and what they meant by that was to write something based on it's merit and being objective. I didn't realize how much I learned from those assignments until I was faced people who write reviews in real life.
Most people in real life, don't write objectively about the things they love, hate, or feel meh about. They write with emotion because the things people hate or love make them emotional. There's nothing wrong with that! People are entitled to respond to things however they wish. Today I wanted to share a sentiment about why I myself don't hold a ton of stock in what others think or have to say. If I did, what kind of artist would I be?
All in all, if someone felt that strongly (good or bad) to leave a review of my books, that's awesome. Of course, people who sing praises all day are wonderful and having those people around are fantastic! We need more of those, but there are people who won't like your stuff and you've got to have a way to filter through that. For anyone that's reading this and is afraid of what others think, remember to find the good in any situation. It doesn't matter what other people have to say as long as you know what you're going to say. :)
