Don’t feel guilty about having side projects or side interests. They may be more important than your main work.
Although I am taking three classes this semester, I value the most the casual Latin reading group that meets every Friday afternoon. The reading group encourages me to practice translating neo-Latin texts, such as Boccaccio’s De mulieribus claris. The three courses are informative and enjoyable, but I find the Latin group to be the most intellectually rewarding and the most necessary for my field. A medievalist must know Latin.
In the U.S., PhD students have 2-3 years of coursework before starting work on their dissertation. It is so easy to ignore your intellectual and professional needs when you are in the process of fulfilling course requirements.
Of course, not every course is unrelated to your interests. The courses I’ve taken have introduced me to important texts and scholars in the Medieval/Renaissance discipline. I have had to write a lot. This post is not intended as a dismissal of coursework (I think it is very important), but as a reminder to evaluate how your courses influence your personal goals. Furthermore, there is no shame in valuing certain intellectual pursuits over others. Even though the Latin reading group is entirely optional, I take it very seriously because I want to improve my language skills.
Don’t neglect your assignments and responsibilities, but do prioritize the things that are most important (at the moment) to your professional goals. Learn a new language, practice creating a website, take a coding course in the summer, write for popular sites. Your future employer will not care what courses you took but what skills you acquired.
Don’t feel guilty for knowing what you want and working toward it. As long as you are fulfilling your teaching/research responsibilities and putting a reasonable amount of effort into your coursework, you shouldn’t feel bad for having a hierarchy of priorities.
My main priority this semester is learning Latin.
