As a lowly undergrad, I have had very limited exposure to the Real World of Professional Stuff. However, in my freshman year, I scored an awesome work-study position at the university library. I was like "Eh, how hard could it be?"

Answer: Hard. Very. I was completely taken aback by all the work that goes into actually running a library; you don't notice it as a patron, since libraries are generally calm, quiet places full of coziness and peace, but it's a lot of freaking work. Our library has four floors plus an art gallery, and we were painfully understaffed, so there was always, always work to be done. Eventually, I turned to the head librarian and asked, "How the hell do you do it?"

Her response? "First, you need a Master's Degree. After that, the hard part begins."

tl;dr version: My hat goes off to you.
