How to travel the world cheap?

In really we have a lot of variants for cheapest traveling.

Ways to Travel for cheap:

1) don`t eat! forget about food :P
2) don`t buy tickets for any transport, walking by foot (6 km/hour it`s the best speed for traveling)
3) don`t use sleeping bag and tent, you can climb on the tree and hug soft branches=)
4) if you want to be safe, forget about shower and water, everybody and all animals will run away from you, it`s really safe ;)

I hope my advice will help you!
