The Countdown Begins

I'm posting here just for the sake of posting here. There is exactly one month before I leave Toronto for my Canada World Youth adventure. I've gotten my shots, I've learned a couple of phrases of Spanish - I'm planning to dive head-first into language immersion. It's the most natural way, for me anyway. I've told some people from Latin America that I'm going there without any knowledge of Spanish. They responded with horror on their faces, I've read up on some of the history/culture of Nicaragua (okay fine I read the first part of a Lonely Planet book. And a kids' book, part of series of Introduction to the Countries of the World type of thing).

I feel as if I'm missing something else to prepare me for this, but how does one go about preparing to travel, exactly? There's the packing. There's the documentation. There's the language and history learning. Sometimes there's the shift in mindset. In any case, I travel to adapt, change, go with the flow. I am of the opinion that underpreparation is better than overpreparation.

Edit: I've included a countdown widget:
