I was working eighteen hours a day, seven days a week, trying to build a business, expand our coverage, and bring in investors. But my life, I realized, was out of control. In terms of the traditional measures of success, which focus on money and power, I was very successful. But I was not living a successful life by any sane definition of success. I knew something had to radically change. I could not go on that way.
