I have always found his Millionaire Theme Hours to be interesting. However I get the feeling there are many who get screened out because they used debt to help them achieve their million(s). It seems like the only ones I have heard who say they used debt were people who used debt to purchase real estate (single family, multi-family, commercial) which doesn't surprise me given his love for real estate.
Some of his questions do seem a little odd to me though, particularly asking what was the most they spent on a new pair of jeans. Not sure how that part correlates to becoming a millionaire.
