I think about productivity a lot. I wrote up my productivity system about nine years ago. I created todo.txt apps for iOS and macOS. I have strong feelings about how to stay productive. Because of all this, when I don’t feel especially productive, I stress myself out about it more than I think I should. I even stress out when I feel like I have had a productive day but think that it took me too long to do that work. Instead of feeling good, I end up feeling bad. Instead of feeling like I moved ahead, I feel like I fell further behind. This happens to me all the time. It makes me wonder if all of my thought and hard work trying to eke out more productivity is worth it.
