Success Master Skills - More Passion, Less "Balance"?

Great post on work-life balance at Journey of a Serial Entrepreneur. Makes simlar points to a few of my own remarks in my review of Pete Peterson's new book. Usman Sheik is a startup founder and loves his work. Like many successful people, he sees the lines between work and "the rest of life" as blurred. There is work-as drudgery, and there is work-as-passion. And when work is your passion, there may not be as much need for "balance".
