I remember when I was in college I was so scared to walk into my classes. I’m also about 100 times more outgoing now than I was back then. But I think part of the reason for that is because I forced myself into a situation where I needed to be outgoing (moving to LA and knowing two people isn’t exactly the best situation for a shy person). I wasn’t shy around my friends but…who is. You almost just have to realize that no one needs to know you’re shy. No one needs to know how nervous you are. They see what you output, if that makes sense. I’m not saying to change who you are, if you’re introverted then that’s totally fine! Be nice, be friendly, and don’t be afraid to open up a little. Being afraid of what people will think of you will hold you back from so many things now and for the rest of your life. Regardless, if people are judging you, those are clearly not people you want to be around. If there is an opportunity to talk to someone just go ahead and say something. Ask them how long they’ve gone there, what they did over the summer, what they like to do, what classes they are taking. Small talk is usually uncomfortable but it is also the ice breaker to bigger conversations. Good luck!
