I recently had reason to recall the wisdom imparted to me by a friend during graduate school. My end stage was not pretty. The dissertation writing was going on a lot longer than I would have really anticipated and I was basically trying to make something out of a bunch of negative findings.
I'm sure I did a lot of complaining to my friends. For......oh it had to have been months.
At one point one of my friends just said "Why are you doing this? If it is so horrible and you hate it....just stop and do something else."
There was probably no way I was ever going to just quit. Not in the cards for me not try to earn my PhD at that point of the process.
However, it was a good thing to hear. It really did sink in after awhile that I had to decide. Did I like the job? Did I like doing this horrible science thing when it was going shittily? If not, why in the heck wasn't I bailing to do something I found more interesting?
I still complain about my job. Don't get me wrong, we all like to blow off a little steam now and again. I get that.
But I am grateful for the guy who long ago put that little voice in my head that pulls up the reins after a certain point has been reached.
If you don't like the job, why on earth are you still doing it?
I had to grit my teeth and grind out my dissertation year.
I've had to grit my teeth and grind out more than one interval of time in my career since then too.
Grind, my friends. Grind it out.
