I guess it all depends on your definition of "successful". This guy was successful in building the system of his dreams/everyone else's nightmare, but at the cost of a meaningful and fulfilling relationship with his family. My worry about my record cleaner finally kicking the bucket doesn't get in the way of even the most mundane family matter. My kids are 21 and 23 and I am 100% confident that we will never be estranged. I have a wonderful, honest and comfortable relationship with my wife of 25 years. I have a wide circle of friends, some of which are music/audio enthusiasts, and more which are not. As far as I am concerned, I am a tremendous success.
If your definition of success is wealth, you have been duped. I think a lot of what we are calling "obsession" is just somebody being a self-absorbed jerk.
