1. You will learn how to use every available space
Considering the lack of size and amount of space you will have when you take on roommates it is important to learn how to use space wisely. You might not get a full closet, you might have to share a dresser, and you may very well have to use what could be kitchen cupboards as a place to store your one coffee mug along with several other items that are anything but food related. If there is a square inch of space in your apartment it will be used eventually.
