On a somewhat side note I highly recommend Traveler's Tool Kit by Rob Sangster. It's a bit dated but I really like the way he writes and his information is general enough to be applied anywhere.
My tentative itinerary is into Bangkok then north and over into Laos, then down Vietnam, maybe into Cambodia, back to Thailand to go to the beaches in the south, head over to Malaysia for a bit, and finally to do some WWOOFing in Sri Lanka. I still am unsure if I am going to Nepal to do the Annapurna trek.
I have been extremely nervous the past week and only grew excited when I received messages back about people inviting me to sleep on their couch. I guess it's always nice to see how welcoming some people are and to feel a sort of connectedness even though I have yet to meet them and only have travel in common. Even as of now I am not sure if I am looking for something or taking a young mans adventure (coming of age kind of stuff). I do know that foremost I simply want to travel and test myself, hopefully meeting some good people and trying some delicious, though exotic, food along the way.
I'll just scratch this itch and see if it doesn't turn into a disease.
