Then what?
I was asked yesterday what I planned to do when I got my degree. The question was then reworded to ask how I plan on using this doctorate. The truth is that I don't know. My primary goal is to increase my salary (hopefully enough to offset the debt that this degree requires). I haven't really thought about "doing anything" with it other than hanging it on the wall and every once and a while condescendingly saying "It's Doctor Marks to you."
Those aren't very noble goals.
While I am now suffering a bit of existential angst in regards to my role in the cosmos, I am largely shelving this dilemma for the time being. I need to get the degree first.
