From Workstyle (which unfortunately requires an account in order to post comments), The Pentachronic Time Scale talks about the five categories of time in which to do a task.
It’s a simple post, but it sure gets you thinking! How many tasks should be in the first category? How many Someday/Maybe projects are sticking around on your list of things to do that shouldn’t be there? And what should be put under the last category that you don’t currently have there?
Do you have a quick task that isn’t being done Now? Are you going to do it Sooner or Later?
Have you been worrying about an uncompleted task? Nothing can be more tiring, but maybe you can decide that it isn’t worth doing. Problem solved! No more stress! No more fatigue! If it is worth doing, then you should decide when to do it. Then do it!
