Have spent a lot of my life doing manual labor, and still slightly in that boat now but do have a proper office job (receptionist). it was incredible for me to experience my first office job and realize this general fact. Not only was my body not sore everyday, but my day was suddenly largely my own, my "labor" was suddenly not defined necessarily by constant action. I dont even really have to think as much as I did…
But in some ways, it's the source of ongoing frustration. Office culture IME is not very interested in getting direct work done. When I was on the McDonald's breakfast shift, I had a solid block of hours where people knew not to bother me unless something was literally on fire. I could get into a glorious flow state. Even managers, even visiting execs knew to button their lips until the time was right. But these days? There are so many people who are happy to put 30 minutes on my calendar or interrupt me on Slack. They mean well; they just don't know anything else. How I wish they did!
