Both my sons did better in college than HS. They were well prepared, and found the taking classes in subject matter they were interested in–and thinking about preparing for a job and life–really turned up the effort and desire. As to being lonely, use college as the amazing opportunity it is to connect with people your age, with diverse AND similar interests and backgrounds. Think of yourself being an “arms open” person, start up conversations, develop an elevator pitch about yourself, ask lots of questions of other people to spark conversations. Try new things. You will find your people!
