I mostly played video games in between intense bursts of productivity to get work done.

Yes, I was doing this before remote work was a thing. You just have to be slick. I once set up a “lab” of three PCs to “test some new software” in a back room and then played Birth of the Federation on one of them while the other two ran perf counter output, for 3 months straight. This was an act of desperation to keep my mind busy. They had laid almost everyone off in the company so I didn’t have much to do, but it started a tradition that carried me all the way to retirement!
