I filled an elective spot with an anthropology class and felt like I finally found a discipline that thought and observed as I did. Half-way through that semester, I swapped my major for that (I was a first sem junior,) added sociology before I even took the first class. In all these years, and despite a tech career I loved, I still feel the social sciences are my academic home.
The class that changed me intellectually- when I had to repeat college physics (I wasn’t about to dissect and hated hs chem. At that point,there were no other options.) They had just changed the gen ed to a brand new practical class taught by a young PhD candidate. The topics came alive. I thrived. Now it made sense. And eased me into the tech world.
