Travel is surprisingly cheap, provided you don't spend your time in 5-star hotels. This month in Belgium will cost me about 850 euros including food and rent, which isn't too far off from living with a roommate in Los Angeles, my previous home. Go to Vietnam and you'll live like a king on $500/month. Oftentimes the most expensive part of the trip is the plane ticket. Of course still not everyone can afford to do this; but if you can, then you'll find that doing so will be a landmark in your life, even if it seemed very scary at first.
