The hardest thing so far as a blogger and author has been to keep the negative opinions and reviews out of my head. Even though I know that 99% people love the food, the book, the blog recipes and do let me know, some comments or reviews just get to me.
For example with my book, some not as positive reviews means it is reaching many more people than the intended audience. But reading them is not fun. Sigh, reminder to self, one cannot please everyone. Just do what you do.
