1. Get to know the Swiss - they might be a little hard to get to know at first, but it is so rewarding.
2. Visit the Great Escape - it's one of the key 'hangouts' for the University students of Lausanne
3. Travel and see Switzerland. See other countries too, but there is so much to discover in Switzerland.
4. Stay in FMEL accommodation either Cedres; Rhodanie or Bourdonnette (and stay in a shared apartment where possible because you'll meet great people).
5. Try things you wouldn't normally try, because they are the memories you hold on to. Don't just step outside of your box, jump out with abandon.
