Attending college is an extremely exciting time! College is one of the few places where you will likely meet people from many different walks of life - my biggest piece of advice is to take advantage of that - meet as many different types of people as possible. The friends you might meet in the dorm freshman year can often becomes friends for life. The second piece of advice I have is to take the opportunity to get to know your professors. I went to a very large school where lecture halls often had up to 300 students, so I never really had relationships with my professors. My friends at smaller schools had the chance to really build relationships with professors and many still keep in contact today, after 10+ years. If you do go to a big school, try attending office hours and taking advantage of other ways you can introduce yourself and build relationships.
