Your title determines about 70 percent of your book's success. Good titles attract readers. A bad or ill-fitting title is like a dunce-cap on your work. And the author's choice of title is not necessarily the best one.
F. Scott Fitzgerald wanted to call his novel Trimalchio at West Egg. His editor changed it to The Great Gatsby. Napoleon Hill called his "how-to" book Use Your Noodle to Win More Boodle. It became a bestseller under the title Think and Grow Rich.
