Don't be discouraged by bad reviews. I am not referring to the two word reviews that simply state, "It sucked!" But, a valid bad review can be very helpful. There is always something positive you can take from it. I once had a reviewer write two full pages on all the reasons she hated my book. I read it and almost cried. She said if she could have given me a phat zero rather than a 1 star, she would have done so. I slept on it. The next day, I read the review again. Her criticisms were valid. In reality, I couldn't have paid for a better, more astute and constructive critical review of my work. I used every free suggestion she made! And, the book is now getting five star reviews.
