I'm gonna be a senior this upcoming year at college. Seriously I know it sounds lame at first, but just do random clubs / intramural sports that sound fun. Whatever you are interested in. Also, you'd be surprised how far small talk goes when your in classes with people in your grade, or just any other random spot. Freshman year everyone is in the boat, and it's unreal how nice/friendly everyone is because everyone is looking to fit in and make friends. All of my good friends throughout college have been people I met my freshman year. Enjoy it
