A given book is not always valuable to every person. A book that changes my life may bore you or not apply at all. This is why there is a marketplace for all types of writing.
With that disclaimer, I will list books that have made an impact on me and that may well be of help to you as well. This list will grow over the years, so please check back periodically. Also, please share the books that have meant a lot to you. Once I review your recommendation and agree that it is a fit, I will add it to this list.
