You will miss people (and huge life events) back at home
Get ready to miss new relationships, bachelor parties, Super Bowl parties, weddings, new babies, the works; and slowly you’ll discover, which of your friends will and won't stay in touch. It takes a lot of effort to maintain relationships with people back home, and sometimes you might be the only one putting in that effort. But remember: notes, postcards, and Facebook messages go a long way.
Don't take cultural differences personally
People might seem closed off, which can make them appear rude or disinterested. But that's not necessarily the case. They may give you a brutally honest answer, and tell you bluntly that your urban mullet isn't a flattering haircut. It could just be the culture. Employees at stores or restaurants might be distantly polite, on their cellphone or talking to friends, but never making small talk or checking in to see if you need more mustard. Don't sweat it -- it (most likely) doesn't have anything to do with you.Then again, it could. Either way, get over it.
