If you find that you’re reluctant to permanently give up on to-do list items, “deprioritize” them instead
I’ve found that there’s value in having short to-do lists, because short lists fit much better into working memory and are thus easier to think about. If items are deprioritized rather than getting properly deleted from the system, this increases the total number of to-dos one could think about. On the other hand, maybe moving tasks to offscreen columns is sufficient to get them off one’s mind?
(Granted, lots of text editors have affordances for going through a document’s history to retrieve deleted text. But I find them a hassle to use.)
It seems to me like a both easier and more comprehensive approach would be to use a text editor with proper version control and diff features, and then to name particular versions before making major changes.
Whenever I look at a to-do list, I’ve personally found it noticeably harder to decide which of e.g. 15 tasks to do, than which of <10 tasks to do. And this applies to lists of all kinds. A related difficulty spike appears once a list no longer fits on a single screen and requires scrolling.
