I am indeed real, but if you want my full analysis, I hate to say it, but you should really consider buying the book. One of the reasons I wrote it was to offer that analysis in detail. The short version of my answer to your question is that you really already answered it--you have to define success first. Mark has succeeded at things I've failed at, and I've succeeded at things that Mark has failed at. Does that make one of us "better" than the other? In monetary terms, maybe eventually, but even those terms haven't been strictly defined yet for the time being. In moral terms, I think there's a clear answer to that question, but it's not going to yield a number for you. Besides, who says that everything has to be quantifiable? Some things in life just aren't.
