Perhaps travel cannot prevent bigotry, but by demonstrating that all peoples cry, laugh, eat, worry, and die, it can introduce the idea that if we try and understand each other, we may even become friends. Sometimes it's a little better to travel than to arrive. My own journey started long before I left, and was over before I returned. Every perfect traveler always creates the country where he travels. There is one voyage, the first, the last, the only one.
Every obstacle yields to stern resolve.
He who is fixed to a star does not change his mind. You got to be careful if you don't know where you're going, because you might not get there.
