Back in 2011, I formalized what I now call Fundamental Truth of Life #4: if something is stressing you out, stop doing it.
Two weeks ago, I quit my Chinese class. If was killing my Mondays and Wednesdays, which should be prime dissertation-writing days. And when I found out that even the Internet-based HSK exams have to be taken in person for some reason, I backed off on my plan to take HSK-2 this summer, since we're uncertain what our financial position will be (making a trip to Miami difficult to justify). I'm still studying Chinese on my own, and I intend to attend classes again in the fall (assuming I'm still at this school in the fall), but for now, I've taken one more step in quitting my way to success.
