Regularly I will post a book-marketing tip, usually with questions to stimulate your strategic thinking. Here is the first one: It took Thomas Edison more than 10,000 attempts to invent the light bulb. He said, “I have not failed. I finally ran out of things that wouldn’t work.” He succeeded because he persisted as he learned from his mistakes. What are the biggest errors you had in the past year? What did you learn? What opportunities did they create for you? What mistakes might you make on your current project? How can you use that information to help you reduce errors this year and sell more books?
