I think we are all human - but my bosses might think otherwise! For me, it's a little more challenging than the rest because I am more introverted than most people, so I need to step out of my comfort zone and do things that are not so natural to my usual self, e.g. making small talk. At the end of the day, it's a job and I just have to be professional about it.
Yep I agree with you, when it comes to our jobs we need to push the envelope a little, be professional, and that may take us out of our comfort zone a little. It's not a bad thing, but can seem very awkward.
