What do i need to do to get prepared for backpacking around the world with my friend? money wise and all that.

Depending on where you are from and where you might be going, you may need to prepare to experience extreme poverty, incredible kindness. You will need visas, innoculations, guide books, but also need to do some planning. No on can tell you the best places to stay, it depends on what you want to see and what you want to get out of your trip. have fun
