Recommended Book: Selling Put Options My Way

I finished reading Selling Put Options My Way by Jerry Lee. The author has had great success with a simple trading formula. Basically, he uses his margin maintenance to sell puts on solid stocks 20% below  there present price. He only sells near month strikes so the stock would have to collapse for him to lose. If one were to follow his criteria it is credible that one could make 2-3% per month. Yes, you read that correctly. There are other criteria and he sets forth exit strategies. I've been doing this a long time so new insights are harder and harder to come by. I did find this book to be interesting and I've stirred it's contents into the soup that is my trading strategy. Happy New Year, Chester
