I like to challenge myself.

If I do something, it's always 90% obvious and 10% unknown.

Never accept your limitations - because there are NO limitations.

As a little kid, I climbed a lot of trees because I always loved the bird's-eye view.

When I was standing there on top of the world, you become so humble, you do not think about breaking records anymore, you do not think about gaining scientific data. The only thing you want is to come back alive

I'm not an adrenaline junkie. It's never been about thrills for me. I'm just someone who loves a challenge.

We want to push mankind's boundaries out a little further.
