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.

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'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."

On my very first day at T-Mobile, I demanded that every time I spoke publicly to the company, all employees across the country would be invited to watch. I faced legal and all that crap, but ultimately we were able to figure it out. We record it, too, so if somebody can't leave the sales floor, they can watch it later. Another thing I did very early on is give every employee stock, which we continue to do. So every time I speak to them I speak way over some of their heads.

Part of my role at T-Mobile is the ability to just be myself, because I'm 58 years old and I've done very well, and I don't need to fight my way up the hierarchy with my suit and hair anymore.

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.
