So many books affected my life in some way. In my younger years it was books by Isaac Asimov, Frank Herbert, Ray Bradbury, Mary Stewart, Stephen King, Arthur Clarke.
And at the top of the list is JRR Tolkien. Every book and story still strikes a chord with me.
Another book that really hit home was Meeting Rozzy Halfway by Caroline Leavitt. Have read it many times. Hurts my soul every time.
And this book changed my life in a big way. The Easy Way to Stop Smoking by Allan Carr. It helped me quit smoking cold turkey after being a heavy smoker for almost 40 years.
