If you feel this way, I can imagine you look like Grumpy Cat.
I took a break from the "Screw You Rejections!" phase. Ahh, it's nice to breath. I'm just kidding. For real, rejections are a part of it.
Almost like anything you do. They are there because they have to be. Imagine all the crappy writing that would be out there if there were no gate keepers? Imagine if my first book was published! Imagine if I wouldn't have been able to change it.
So now, it's more like...
"Thank you rejections, you make me stronger!"
Have a flashy day!
