How do you answer the question: "what is it that you do?
I don't know about you but, I used to be really bad at explaining what I did for living. It just seemed impossible for me to answer to answer this simple question succinctly. I would go into way too much detail, ramble, become awkward, get my tongue twisted and frankly just weirded people out.
I was worried also that, when answering this question, particularly in a networking setting, I would come across as being too salesy.
Frankly, I would rather stick pins in my eyes or at least find a way to change the topic as soon as possible.
