I did this in my mid-20's and it was indeed a great way to travel. Ended up going to 50 countries before I turned 30. Lots of CouchSurfing along the way, although that community/site has degraded. Had an Osprey Escapist 20L backpack which was more than enough to fit a weeks worth of living into, I'd do laundry and buy new t-shirts/underwear along the way. After years of traveling I think I ended up being every type of cliché traveler eventually. Doing the math it was about $15,000 CAD / year. It was actually a very interesting way to live and it gave me a lot of confidence to be able to survive in most places on very little. Even the most expensive cities in the world you can usually find a way to live cheap, if you are willing to compromise and find a way to be ok with being uncomfortable.
