This may sound nauseating, but I am a very happy person. I love my work, I love my life and I'm told by those who know/love me that it's a bit like living with Tigger. Bloody annoying, I should think.

On holiday in Spain with my family about 20 years ago. Sad, but true.

Happiness is planting the vegetables, sleeping with my girlfriend, running, doing my work, sitting by the fire with a book and a glass of wine... I need a reason to be unhappy, but do not need one to be quietly cheerful.

Right here, right now.

My surname. You have no idea how many versions I’ve read and heard. It was especially irritating during my Abba years. You can imagine someone calling our hotel and saying: “I’d like to speak to one of the guys in Abba.” Who do you think the receptionist called, Andersson or Ulvaeus?

Bill Gates. Not only did he build Microsoft, he went on with his wife to create the Bill & Melinda Gates Foundation. They support the, in my view, single most important factor in making the world a better place – empowerment of women and girls.

Successful like my two uncles, who were paper industry magnates.

It’s a calm and secure feeling of deep loyalty.

A cabaret act with Agnetha, Frida and Benny. It was in a nightclub in Gothenburg and one night we had seven in the audience. It was before we found out that we were a pop group.
