I can't stress enough how amazing traveling can be - and I recommend that everyone do it at least once! No hotels or planned excursions: go somewhere, figure out how to say "please", "thank you", "excuse me", and "I'm sorry, I don't speak..." in someone else's language; learn how someone else's currency works, try someone else's cuisine, shop in someone else's supermarkets, go explore! You DON'T need to be rich to do it!! Save up some money (for my American friends especially), find a cozy hostel, and go with a tight budget to discover the rest of the world. Your mind and soul will thank you for it.
