We did start with a simple manifesto, as we called it, which was a description of what we were about, and it was the Un-carrier. It was about finding and solving customer pain points in an attempt to fix a stupid, broken, arrogant industry. It was something we felt passionate about. It was our goal to make changes and have the industry make the same ones.

Strangely, from a life-change standpoint, I sold the company I was running and got divorced in the same month. And so there I was, at home, and I'm not the CEO. I took a few months thinking about what I wanted to do. When the first call came in about running a company owned by Deutsche Telekom, I thought it was laughable and really not something I'd do. I took the meeting mainly because the headhunter I knew. At first I thought I was just helping her fill out the roster, but then I dug into it.

I'm very careful, especially with the company, to not spend too much time playing the success reel because I really do believe that everything that's been accomplished can be parlayed in an equal amount going forward.

T-Mobile is a young, consumer-driven business, and the average age of my customer outside of Bellevue is 27 or 28. They like outspoken, frank discussion. There was an event where it started to come together, I thought the audience would only care about the MLB guys, but they wanted to know what was on my mind. And I literally snapped about the state of the wireless industry. Over the next 24 hours, there was a lot of stuff that was coming out of my mouth that was meant to stay in Vegas, but it hit a chord. It was an action statement for me that I was going to fix this industry.

When we're talking about the transformation, we can add in the 25 pounds I've gained - I've been eating my way through the wireless industry.

If you go back in my career, you'll find I've always been a lead-from-the-front people-manager guy. I've always been outspoken. I've always attempted to break the mold. My advice to myself, then, would be to go all in on it. The world doesn't need another cookie-cutter business-school leader. The world needs somebody to stick out and be loud and proud.
