The best thing about travelling to me is that it teaches you to accept everything as it comes. Mistakes become blessings, because for every wrong turn - you arrive at something you wouldn't have originally found. You miss the train, or it gets dark while you're hitch-hiking, but then you meet that one person who saves you, and becomes the beautiful face of humanity all of a sudden when you were just starting to panic! And you wouldn't have made that connection if everything had gone to plan, and those are always the most memorable moments. :)
Haha well that's my experience, from travelling with no money, the best way to see the world. You learn a lot!
