Middle Class Millionaires and Business Coaches

I recently posted on the book The Middle-Class Millionaire.  One piece of information from the book that really surprised me was the extent middle-class millionaires (defined as having a household networth between $1 and $10 million dollars) use business and personal lifestyle coaches. 

Their survey showed that "about half of middle-class millionaires have hired a business or life coach in the past three years, and another 20 percent or so say they intend to hire one in the next few years."  The primary purpose they cite for hiring a coach is "help with career skills (90 percent)." 

We've been following the trends around the growth of personal services, but I wasn't aware of how common business coaching had become.
