It’s all about focusing your time and effort on things that matter, and reduce the friction in making decisions (which take a non-zero amount of time and mental effort). That way, I do not spend time thinking about doing something, or reminding myself to do it on a constant basis - it’s in a trusty notebook, that I can check at any time to see what’s there left to do. This reduced the amount of time I need to spend on trying to get the sound working, or play audio from my phone to the home system.
