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.

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.

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.

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 think this job at T-Mobile has more than anything else helped me really see and understand how to set a strategy, communicate like crazy, and then passionately lead from the front of it.

When I finished my last job, at Global Crossing, it was the first time in God knows how many years that I wasn't in a job. It was probably 32 years or so, and there I was, it was like pow!
