I find there is no one book that will give you the "Golden Answer." A combination of material mixed with the book of life experience should certainly be of value. There are so many books on the market and most of them assume the readers level of acknowledgement to be what ever may or maynot be. I don't think I'm allowed to recomend any products in this forum. I contend that you are in the right place for questions and answers. Here in this forum is much better than a book, because you can get diverse opionions on what ever specific topic. Ask direct questions and you'll get answers.
