My book was to scare you into taking that trip, not motivate

Take all the sexual gear you need.. condoms, lube.
Earplugs for sleeping in loud dorms.

At least one outfit where you look sharp.

You won't have room for two weeks in a backpack alone. But you can add a duffel bag to the mix. I don't travel light but I like having options, looking somewhat decent, and not having to do laundry ever 6 days.
