When I published my first book, I wasn’t a newbie to public critiques. I worked for a newspaper and wrote a column on parenting - two places where trolls live in the comments section. I knew how horrible people could be, and had developed a somewhat thick skin over it. Don’t get me wrong, it never feels good when someone publicly blasts your parenting decisions or even your children. But you just have to keep reminding yourself that trolls feed on creating a reaction. Delete, and move on. It's different with reviews, though...
