Sometimes you have to go up really high to see how small you are.
Don't live life as a spectator.
I like to challenge myself.
The only limit is the one you set yourself.
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
If something goes wrong, the only thing that might help you is God.
