I think your idea is quite interesting.
On the other hand, it occurs to me that we might be making a dangerous list of "should's", where in my opinion I like to direct my life towards "wants" and "feel likes"
In that sense, I tend to wait for many of those tasks to kind of blow up so I know there's no escape. Instead of having every little detail impecably handled, I just focus on the important stuff, and neglect details. Then, I don't have a shirt to wear the next day, panic a little, solve it, and that's it!
But in the end, I'm almost sure I haven't wasted any more time that just the absolute minimum needed to handle details.
That being said, I also agree that some are better me handled in a cyclic way. For instance, I go to the dentist every year. Calendared, handled "properly". It pays off. Many of other examples I had in the past don't, and were filling my calendar with an ocean of "should's", almost making me feel like a robot controlled by my recurring tasks.
Anyway, here's my small contribution to your collection with some recurrent tasks I still use and have calendared:
- personal financial control (monthly review)
- cut hair
- buy flowers
- monthly lunch with university colleagues
- car inspection
- visiting my ill aunt
- visiting the ocean for no reason
- changing winter/summer clothes in the closet
- (at the company there are some more: board meetings, department meeting, ...)
P.S: I have a maid cleaning up weekly - that of course sorts out many...
