I always loved watching the Champions League, growing up.

When I was growing up, I was focused on football and school.

No matter how good you are, your mentality has got to be right. A lot of young players, that's where they go wrong, and that's what I've always seen when I was growing up - players who are almost there but couldn't quite get there because the mentality wasn't right.

I feel I have been very lucky. When you are growing up, you have dreams of being a footballer, perhaps even playing for the club you support, and I am living that dream.

During my study of happiness, I noticed something that surprised me: I often learn more from one person's highly idiosyncratic experiences than I do from sources that detail universal principles or cite up-to-date studies.

We had four guys in the family, so somebody was always hitting somebody or chasing somebody or getting mad or fighting or wrestling - that was just what you did. So when you're the youngest, it's good for you. You figure out real early how to get out of headlocks and holds.

You don't teach morals and ethics and empathy and kindness in the schools. You teach that at home, and children learn by example.

I was one of those weirdos who, at six years old, was telling everybody that I wanted to be an actor. I saw my sister in a play and realized that I wanted to play make believe in front of people; I was always goofing around and putting on shows for my family.
