I self-published my memoir and used Amazon's Create Space to format it. I would never do that again. There were different eyes on my book throughout the entire process, and it took forever to get my changes made. I would choose a talented person through LinkedIn or another contact to do it next time. I also paid an editor and a copy editor to ensure I had a quality product. I made all of my investments back and then some, but it was because I had a platform with my historic bar and grill. Promoting your book is more exhaustive than writing it. As soon as you stop, it dies on the vine. I sell more books on my own now than on Amazon.
