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.

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."

When I used to live in Asia, they used to say, "If you're going to sing karaoke, you want to go after the worst singer." And I'd be coming in Deutsche Telekom after the worst singer.

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.

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.

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.
