It is worth the money. Mike cuts right to the chase with this line,"you are in the electrical contracting business to make money". I also have the book, but haven't been able to spend much time with it lately, but what I have read is good enough to know that it is money well spent. Next for me, the MH DVD set to learn even more. My ultimate goal when I can is to buy all of his DVD sets for the books I have. I wish Mike Holt enterprises had a satellite branch in California, as I would love to attend one of his seminars. Another future goal.
