This expedition is only reserved for people who dare to believe in themselves. He who is not willing to question his certainties and his convictions cannot join and keeps his seat. He who thinks he cannot change yet because he is just as he is, will never start and he who never starts never will arrive. He who believes he will never find the way out, will stay wandering in the labyrinth. He who believes in progress can never follow the track back. He who believes he can never get rid of his luggage will carry his burden to the last gasp. He who keeps believing will never know but he who will seek faithfully will find.
