Newest Admin on the Block

I was hired by my company to do data entry. Now, almost a year and a half later, I find myself an administrative assistant to one of the vice presidents of the company. Yay me! Only thing is, I've never been an admin, or even worked with an admin. I really don't know what I'm supposed to be doing. It hasn't stopped me so far, though. By some fortunate combination of useful skills and blind luck, I'm praised for my "unique and creative approach to problem solving." Hey, it works for me!
