Today will be all about feeding your brain, and you should waste no time exploring topics and people you don't know very well. If a conversation drifts toward foreign ideas or weird sports, try to keep up with it. Even if you're not exactly sure what everyone else is talking about you still can offer some input: even if it's just to say that you need them to explain things to you! The brain is a muscle, and yours is capable of getting a body-builder's physique.
