Get out there and do something fun!
The MBA is not just about reading, studying, attending lectures, working on group presentations until midnight and dreading about the next deadline (although especially in the first half of the FT MBA, that is all that it seems like). It is also not just about finding the perfect job after graduation. Your experience here should also include spending some time (if you have any money left after tuition:D) experiencing the great country of Switzerland.
There are so many events, especially in the summer, ways to enjoy the great outdoors and travel around Europe, so save a few pennies before starting your MBA to do some of the really fun things. I have been living in Switzerland for nearly 14 months now, and have had a chance to travel quite a bit, but also to enjoy some of the local activities. Here is a sampling of just a few of many.
In August, if you are already in Switzerland, take part in the Zurich Street Parade. A Million people attend this yearly street festival, which is held on August 11 this year. More info here: http://www.streetparade.ch/
In October, make sure you attend the OLMA in St. Gallen. I believe the main attraction used to be animals and local products, but these days it is mainly the huge wine halls, which show case wine from the region, and the numerous fairground rides and foodstands. Don’t miss to have some Bratwurst! Btw – if you miss the OLMA in October, you still have a chance to attend the (smaller) sister event OFFA in April.
At the end of June, there are plenty of things to do (although you will be very busy with your projects by then): The St. Gallen Open Air, The Albani Fest in Winterthur and my own favorite, the Luzernerfest (all of which fell on the same weekend this year). All three are rather different from each other, and I can only speak from personal experience when it comes to Albani Fest and Luzernerfest. Both are free entrance since they are within the respective cities, and there is plenty of free live entertainment going on.
If festivals are not your thing, then take a boat ride around Bodensee (Lake Constance) or hike the rolling hills of Appenzell.
I hope you get a chance to take part in one (or all) of these festivities and activities during your studies!
