I got my first rejection last week. As rejections go, it actually wasn't that bad but I have to admit it was a bit of a shock. Being a writer means that you have to take rejection on the chin and move on. While its a nice thought, everyone will not like your work. Sometimes you'll get a bad review and it feels like a kick to the chest. Your story is your baby, you spend months building it up and making it the best that it can be, then somebody says it's crap and you end up questioning yourself.
All I can say is, take a deep breath, focus on the good reviews and know that you're a talented writer. You wouldn't be published if you weren't.
So I got my first rejection, that day I went over the story and followed the advice of other writers. I submitted it somewhere else. A rejection from one, is not a rejection from all. I'm still nervous about it but it's fine. I'm going to throw myself into another project and pretend that I'm not counting down the days until I find out if it's been accepted or not.
I hope you're all well.
