Sounds like a great idea if not an easy one, right? But it’s very important to do this as a writer no mattter how hard it may be sometimes. As a writer you will get disappointed a lot- whether it’s a book rejection from a publishing house or a bad review from someone who has read your work.
I wrote a short story that I was absolutely proud of. I took an inanimate object and made it into something menacing and supernatural. It got rave reviews from those I let read it, and my pride grew. So I entered it in a short story contest. 6 winning entries were chosen for publication- mine was not one of them.
This is where the shrugging it off comes into play. I let myself be upset for a moment, but only one. Then I shrugged it off and published it on Amazon. Now it’s there for readers to enjoy even if it didn’t win the prize. While I was looking forward to having a contest publication to add to my biography it was okay- I tried and that was good even if the end result wasn’t what I was hoping for.
As for reviews that make you frown? Just remember that not everyone gets your writing style. One of my favorite authors has several 1-star reviews on Amazon, and I know he feels every one of those more than the 5-star ones. The message to take away is that you cannot please everyone, so instead I offer this advice: Write for yourself before all others. You may sell tons of copies or none at all. Be your own biggest fan and your harshest critic, but always write for yourself first.
