But it's funny growing up, because everyone treats you - as twins growing up, everyone treats you like you're one person a lot of times, which can be frustrating. But then I think we embraced that when we were young.

In my professional life, someone I really look up to is Kathleen Finch.

Yeah, well, in the beginning, our mom and dad had one philosophy. We couldn't just sit inside and play video games.

My philosophy is eat healthy. Your body is your temple.

One minute, you're dropping your teenage son off to a festival, and the next, you're changing a nappy, but I love the versatility and challenge of being a father.

When I was nine years old, my father went to Spain to work for three years, and I was in Portugal. He has a sports store. I only saw him once a month, which was difficult. I was alone with my mother and my sister, who is younger than me.

I've always regretted that I never was able to talk openly with my parents, especially with my father. I've heard and read so many things about my family that I can no longer believe anything; every relative I question has a completely different story from the last.

I'm ridiculously proud of my children. More so than any of my books. I suspect I wouldn't have written any of them if I hadn't been lucky enough to have this huge family.
