Here’s a problem I’ve faced recently: my obsessive focus on a small number of important project causes me to fall behind on the annoying little administrative stuff that pops up on a daily basis. I’m not talking about the regularly occurring minutia, like cleaning my apartment or working out: these can be easily handled with an autopilot schedule. I am referring, instead, to the random, unexpected productivity lint that regularly clogs my inbox and emanates a powerful aura of procrastination-inducing annoyance.~ Cal Newport, from https://www.calnewport.com/blog/2008/11/18/the-stable-mucking-method-a-freestyle-approach-to-keeping-the-annoying-little-stuff-under-control/
The important point is that you have some intentional way of keeping up with administrative tasks. If you don’t, these little thorns will pile up until everywhere you look you find sources of stress. Or worse, to avoid the stress, you stop looking.
Newport’s post describes one method—one which I don’t personally use—and links to another post describing another method. The two posts give a good overview of the problem he’s trying to solve, and some thought-provoking ways of trying to tackle it.
