Productivity is knowing which unfinished tasks deserve to remain unfinished.

Part of doing good work is choosing what will remain permanently undone and being at peace with it. An open item that you have consciously decided against is not a failure, it is a decision, and the unease around unfinished things comes largely from never having made that call explicitly.

Take your list and mark three things as deliberately abandoned. Not later, not someday. Done with. The relief tends to be larger than the tasks were.
