I couldn't be happier. I'm so happy, I don't know what to do with myself. Most of the time. I mean, I'm the one who can make myself unhappy. I don't ever want to turn around and say 'if only', so I live my life accordingly.

When my father passed away, I felt the need to drink life, to really get on with enjoying every moment. My dad was a huge personality - a politician in an era when there was trouble in Greece. He was a godlike figure to me, so huge it was hard to keep up. That's one reason I found a better option was being good at being bad.

Life's been difficult in the past. I'm an addict. My addiction took me to some dark places and at one point I had a lot of people after me. It's a tough place to generate strength from, but I found my way back.

I learned to be grateful. It's an easy equation: if you're grateful, you're happy. Sure, I catch myself sulking, whingeing, moaning. My defence mode is, 'Dude, I'm not allowed to do that.' Like going to the gym, the more you train yourself to be happy, the more naturally it comes. From my father I learned you can be happy without anything. At the end he lost his speech, even his ability to read and write. He taught me about humility and strength.

Then there are my twins. Happiness is the smell and smile of a baby. They don't lie. We could learn from that. Babies just say: I am happy so I laugh.
