1. Bite the bullet and buy new clothes. And I don't mean girly dresses and sassy heels, ladies. I mean a parka. Rain boots. A waterproof jacket, gloves, trousers. Let me tell you, the waterproof trousers are pretty hott. If you don't believe that you will need all of this 'gear', go ahead, make the move with only your central Texas wardrobe of tank tops and flip flops and we'll see how quickly you run crying for a shipment from REI.
2. Decide on your expectations of a place to live. Think of what is non-negotiable... what you absolutely, positively have to have. Now take those expectations and just throw them out of the window. Yep, just chunk them out. Don't worry, you'll find a place that is just fine, but it won't meet your lofty (and probably ridiculous) expectations.
3. Save, beg, borrow, and hoard money. A lot of it. What's that you say? You have enough for the first year? You're getting a grant that will help out? Uh huh, good luck with that. Moving to and living in the UK is expensive... there's just no getting around it.
4. Be willing to eat, travel, and hang out with random people you've only met once or twice in random locations, introduced to you by other random people that you don't really know either. The fact of the matter is this: moving to another country (or anywhere, really) can be a lonely experience. It takes a long time for a place to feel like 'home'. Lower your expectations and try to have some fun.
5. Grow out your hair. There are multiple benefits to this endeavour: a) It's warmer. Let's be honest, it's blasted freezing in this country and having a thick, long 'do couldn't hurt. b) It's entertaining. Do you know how many crazy hair pictures you can take before it's not funny any more? A lot.
