I learned a lot of valuable skills that are helpful in many fields, not only in the office. I learned more about Microsoft Office, filling, data gathering and analysis, and what goes into successfully marketing something.
What I wish was different
I wish I could have worked longer days. I had certain projects that spanned several days due to how short the shifts were.
Advice
Ask questions. Asking questions shows that you want to understand and do a great job, gives you a better understanding of what to do and why, and it teaches you things that you can apply in the future, whether it be in this position or another one.
