Don’t think if it as sad but as an evolution. You might not meet the people who interest you until later on. Everyone’s interests and priorities can change – and ultimately, who wants to leave college after 4 years unchanged? And it can take the pressure off to just connect and enjoy people as each day unfolds.
OP, I would encourage you to think about what you like and/or have in common with people as you meet them and spend time with them rather than how you differ. We live in a time when the differences are often the point of focus. Try not to let it be yours.
