This books concepts were to vague for me and almost formulaic. Of course buying low and selling high is the idea, but some of the advice given in here was more designed towards gettign so so or marginal deals. I use very few of this information in my own business and I know of many ways to find better deals myself.
If you were a new investor you might find some value in this book but you are definately not ready to go out and start investing after reading this book.
