Lists...
This is so me and I certainly overuse the Notes app... from work related items to house chores, from places to visit to shopping lists... I have it all.
Most days it helps me relax (just writing it down is helpful) and there is an undeniable breathing space whenever a task is deleted (digital) or highlighted (paper), but at times it can feel daunting too. The main list is somewhat too big, doesn't seem to clear up and that overwhelming sensation starts creeping in.
Some people find it obsessive, others relate to the core, but the fact is that is gives me some sense of control (albeit not always balanced!). What about you? Are you a list maker?
