I grew up in a very large mansion. When I went to school it was so far from home that I could not get back there except on the long breaks. So my parents set me up in a townhouse where I could be comfortable and with a staff of servants so I could entertain guests in a style similar to what I was used to at home. Even so, the small size of the townhouse meant that I had to give up many of the things I was used to having. After all, you can't just pack up the indoor swimming pool and take it with you now can you? And even if you could, where would you put it? So I had to make difficult decisions on what to bring with me. The Lambourghini, of course, and the home entertainment center, the riding gear just in case I got a chance to get out of town on the weekends. Even a large townhouse fills up pretty fast so I left behind the baseball memorabilia and the butterfly collection. Unfortunately, there was no room for my small collection of physics books.
Probably you are going through a similar experience. However, times are tough now and I suppose you will be staying the dorm or whatever they call that place where they crowd dozens of students together in a single building. Here are some ideas for getting by.
The sauna you enjoyed at home is not portable and there is no place to put it in the dorm. Not a problem. All you need is a club membership where they have one.
The dorm will not have stables for your horses. These must stay where they are and you can visit them on breaks.
You will not be able to invite your rich friends over so the best thing is to make do with the other students in the dorm. Some of them are quite friendly in spite of their lack of finish. Unfortunately they won't be able to join you on weekends at the fancier resorts, but trust me, you don't want to get too close to them anyway.
You can't bring your servants. This is a problem because the other students will not pick up after you. In this respect they are a lot like rich people and don't even pick up after themselves. Bring some baggies so you can put your dirty clothes in them and throw them away.
