I went ahead and signed up for the 180 Day Pledge. I hit my 120 days in the fall, and I'll be doing both thesis semesters in 2022 (critical thesis in Spring 2022/creative thesis in Fall 2022), so, honestly, I'll probably hit more than 180 days, but I like to have a pledge level I'm more-or-less guaranteed to meet so I don't get discouraged.
