Well it wouldn't be my worst job ever, as that would have been the day I spent working at McDonalds. No, I'm talking about the worst job I've ever had at my current (and for the past 25.5 years) employer.
Now to properly set this up, I'll mention that I'm an introvert. Make that really introverted. As in "about as introverted as you can get" kind of introvert. In fact, I am such an introvert that I have joked in the past that my ideal job would be a Bridge Troll*. Being an introvert, interacting with my fellow humans takes a lot of energy out of me. In fact, on this very day (Monday, July 20, 2014) I had to do a lot of interacting with other people, which has left me tired and somewhat cranky. And so I digress.
Anyway, I was pondering what my worst job was over the past quarter century. What was it? Easily, it was the year or so I spent working in Accounting. Specifically, I helped develop an asset to liability proof process for the separate accounts my employer offers to customers. This means that I spent all of my time with my nose in Excel spreadsheets working on and with numbers. I absolutely hated it. I was good at it, but I hated it. No offense to anyone that works in Accounting, but the fact that I could do it...the fact that it didn't involve interacting with other humans...meant that I really didn't find it challenging. Again, I am sure that there are plenty of jobs in Accounting that are challenging, but for me, the biggest challenges are the ones that I have to over-come on the inside. The fact that I didn't have to challenge myself by interacting with countless other humans made the Accounting job really stagnant.
Yes, in as much as having lots of "on" time with my fellow human beings takes a lot out of me, it's truly a good kind of tired. Think of it as being the kind of tired that a runner feels after a marathon. Or a boxer feels after a long fight. Sadly or proudly, I seem to have grown accustomed this almost daily kind of tired. Well most days I have; like today, there are still times when the introvert in me screams "No Mas!", but just like that boxer, I'll be ready to get back in the ring tomorrow, guaranteed.
(*) It actually makes for the following very interesting line: "I really don't like people, which is why I work in Human Resources."
