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.

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.

I've given my email address to all 3,000 T-Mobile stores. Serious customer escalations come directly to me. Customers get a kick out of me responding to them, and the employees do, too.

Deutsche Telekom was a brand that people still loved, the nerds loved it, and it was still there, it was still visible. The advertiser was OK. But it was a mess. It was in my mind, though, intuitively obvious what to do. I had some advisers and friends, and we looked at it and said all you have to do is get the iPhone, buy some spectrum, consolidate the industry, reinvigorate the brand, and take this company public.

When I go to T-Mobile retail stores, I jokingly tell the employees that everybody between me and them is the enemy. In effect, what I mean is that in my paramilitary hierarchy, if I can hear them and they can hear me, everything will be fine. All we need to do is make sure the entire company understands that it's their job to pass information between us. And so far so good.

I say that the genius of the marketing strategy that we've had in every company that I've ever been in, is that if you ask your customers what they want and you give it to them, you shouldn't be shocked if they love it.

It's kind of fun at my age to go back and talk to business-school people. I tell them, "I can summarize everything you need to know to lead a major corporation. Are you prepared to write this down?" And then they get all ready. I tell them I can summarize how I succeed as a leader: Listen to your employees, listen to your customers, shut the f - - up, and do what they tell you.
