Too Long; Didn't Read
Why should one want to have a working day organized? Why isn't it satisfying "to simply do what's necessary"? Sometimes it's possible, usually when there are quite a few tasks, and you don't need to communicate with someone else. Most of the time, there is an overwhelming amount of what you need to do, and you'd better know how to balance this. An organized working day helps you do this. Also, some health-related things do not look important today. But many years later, you'll be grateful for the past yourself for taking them into account.
