I have read many books and have learned tremendous amounts of information from them. It is not my intent to criticize my mentors. However, I still made mistakes. So I went back and re-read some of those same books to see if some of the information was incorrect, incomplete or if I simply missed some things. As it turns out, all of these issues were responsible. Laws change and some of the tax write-offs I was promised were no longer available. This affects the bottom line and whether or not you can make money in some of these investments. I don't think the authors of other books intentionally withheld information but consider that most financial books are written after the author has been successful and have forgotten what it is like to start out. It has to be this way for an author to have credibility but I have approached this subject differently. By taking notes for this book since I started learning the new concepts necessary to be successful I can address what the other authors didn't teach us.I want to share the lessons I learned but keep in mind; the laws and economy can change again so your best weapon in investing is your education in the subjects that apply to your investments.
