When you go visiting countries, you start reading the history of the place and you start getting into the culture, and then you have to leave. In my experience, all countries have hidden treasures.

In most sports, your brain and your body will cooperate... But in rock climbing, it is the other way around. Your brain doesn't see the point in climbing upwards. Your brain will tell you to keep as low as possible, to cling to the wall and not get any higher. You have to have your brain persuading your body to do the right movements.

I don't think I'll ever feel as famous or as popular as I felt when I was a 17-year-old soccer player in Modle. Only about 20,000 people live there and 12,000 of them come to every game. Running onto the pitch each week was just the most fantastic feeling. Nothing can beat that.

When I was a teenager, my father went bust. He could have declared himself bankrupt, but he was an honourable man and he insisted on paying back all his debts. That almost ruined the family. I was aware that my mother and father couldn't control things anymore. I guess I was afraid that we would end up on the street.
