Confidence and empowerment are cousins in my opinion. Empowerment comes from within and typically it's stemmed and fostered by self-assurance. To feel empowered is to feel free and that's when people do their best work. You can't fake confidence or empowerment.

Governments can no longer control 100 percent of the story. Time and geographical boundaries disappear. In places like China and all over the Middle East, social-media outlets are being used to expose and hold accountable public officials that don't want to be held accountable for corruption and human rights abuses.

Some people say they have a thirst for life. They're excited about every day and they're prepared to look the bad and the good straight in the face and greet it all with a smile. I like to think I'm one of those people.

I've been known to do lunges down hotel hallways. I also like to use the ice bucket in the hotel room as a medicine ball.

With social media and all the new technology, there's just more interfaces around and reminders to constantly be working on our body.

All the fans that are aware that I'm a family man and I have five kids and the newborn, and they send messages on social media or a sign in the audience, or they just say it to me person-to-person on the street, I appreciate all of that.

It's no longer possible to think of the physical and digital as two different worlds.

The future is in photos for social media. More and more people are not reading, so I try to attach a photo to most Tweets.
