Finally got a job!!!

I’ve been unemployed since November due to covid, and I finally got a job!! I will be working in an office from 9-5 every weekday, but I’ve NEVER worked in an office. Does anyone have any tips on how to transition more smoothly? I’m pretty sure most of my coworkers will be older ladies and I’m 22 so not sure how that will work with trying to make work friends. Not sure if I’ll have my own desk or not, but I assume I will as I am doing data and chart auditing. Any tips to make my space brighter and more cozy, I guess? I just know it’ll make me tired unless there’s natural light or something. Any office tips would be great 😊 I start Monday!!
