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.

My interaction with my followers on social media has become a phenomenon, and that's hardcore work every day! I have carpal tunnel from typing on my device.

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 started to be the brand, more and more. Seven days a week, 24 hours a day, I wear T-Mobile gear. I'm a bright beacon of magenta. My clothing's gotten more elaborate because a lot of people want me to wear their clothes! And then when I go to a call center, I give away my T-Mobile clothes, and walk out to my car with my socks on.

I went, and my first interview was with René Obermann, who was the CEO of Deutsche Telekom at the time - wonderful guy. And right after hello, I told him that it was my opinion that he could only fail one way in the US. I said, "Do exactly what you're doing - nothing."

I tell employee of T-Mobile, "Listen, if some of this doesn't make sense to you, what should make sense is the reason I'm telling you - I respect you as an owner and as a partner and I'm going to tell you this all the time. Feel free to tune out."

I visit T-Mobile call centers. We've got about 18 major call centers in the US, and before I was CEO, I heard that no CEO had gone to physically visit them. I go in, they meet me outside, we take selfies as I stand like a piece of furniture, I tell them about how things are going - but most importantly, I say thank you and help them see that their behavior and their work has driven the culture of the company that's changed the industry and the whole world. It's a bit of a love affair.
