Dan Hesse retired after seven years as CEO of Sprint in August 2014, he vowed to take at least a year "completely off."
The year has come and gone — and Hesse is busy again ... but it's a different kind of busy.
"I'd been accused by many people of being a serial workaholic," Hesse says. "I tried to have a balanced life, but I really focused on being the best leader and mentor I could be. I wanted to take some time to be the best father, husband, son and friend that I could be."
