I would not recommend this book. I was shocked to find that I had paid more than $...for such a poorly written book. It is full of spelling errors (more than 20 in the first 5 pages), poorly structured sentences and poor grammar. And this is written by a professed PHD. Not only is it poorly written, but the information contained in the book is vague and of little use. Most of the information offered could be found on the internet with very little effort. Most of this book is full of personal experiences with very little information on how to actually get started. In fact, this seems to be nothing more than a tease to attend the authors community college course. Again, I would not recommend this book. There are several others out there with very good information at half the price.
