>> for your brain to stop thinking about an unfinished task, you must (1) know and trust that an external system will remind you to perform that task when it is time to perform it, and (2) have chosen the next action taken at a sufficiently concrete level that your brain is no longer trying to plan it out in the background.

Wow, I do this instinctively all the time, but to be frank I feared it was just a stupid obsession of mine and suspected it could be detrimental, that it made me less efficient. I'm relieved to know this is an advised method of managing your mind, even if there isn't of course much science behind it. Anecdotally, this does help with my concentration.
