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.

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.

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.

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.

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.

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.
