Young Professional

I'm a young professional. I don't know my personal mission statement yet. I'm nervous about calling IT. It might take me a couple days to work up the courage. I am trying my best to be professional. I don't know exactly what "professionalism" is. I feel as though I need to continuously work hard in order to earn the paycheck I'm getting. I feel guilty sometimes knowing that some of my peers are performing manual labor for less pay. This is the first time I am not among them. Who are my peers now? I'm trying to interact with my coworkers organically. I'm decades younger than them. I'm getting really good at using the scanner. I copied-and-pasted the email signature of my supervisor and filled in my information. I'm a little embarrassed about the car I drive to work. I went out and got new clothes for this position. I'm not sure what my job is supposed to be.
