Blending in means everything to a lot of people, and I do not know why. We want to go unnoticed by everyone, but we also want to be seen too. Listen, if your a freshman, then it is okay to look like one.
I find it absurd to be afraid of how you look to others your first year in college. What do people want you to do to blend in? Not wear your lanyard around your neck and get rid of all your old shirts with your high school name on them. I know I kept my high school shirts and I was fine.
I did not fear to look like a freshman because I was one. I had no idea what I was doing half the time anyway. The last thing on my mind was if I looked like a freshman or not. It was something not worth worrying about.
Looking like a freshman can be a good thing because then people can tell when you need help. Do not be afraid to ask someone for help. There will be a kind soul somewhere who can point you in the direction of the class you are looking for. Trust me, you are not the first lost freshman they have seen.
Besides, people will figure out that you are a freshman anyway. There are some professors who like to know how many upper and lower classmen are in their class. He or she may ask you to raise your hand if you are a freshman, so it does not matter.
The most important thing is to become comfortable with your university. Try not to concern yourself with whether or not you look like the freshman that you are. At some point, we all were freshmen lost in some way or another.
Lighten up a bit. You will have bigger worries and looking like a freshman will not be one of them. Your grades and getting that degree are your top priorities.
Enjoy your freshman year. Good vibes from me to you!
