Maybe it's just best to let go instead of trying to mini-max your life's productivity, train yourself like Pavlov's dogs with XYZ productivity systems, and guilt-shame yourself over each day you miss out on part of an evergrowing habit list of shoulda-coulda-woulda's.
Maybe procrastination is an emotional regulation problem and tying your self-worth to your productivity leads to more internal conflict between guilt of not doing enough vs fear of failure.
Maybe we could approach improvement out of a place of genuine interest or self-care, instead of treating ourselves like a computer on a cron schedule and then inevitably getting frustrated when we discover that we're human.
In your example, if the number one song is classical and made up 0.1% of listening time, would you conclude that classical music is not popular?
It's like saying water isn't a popular drink because only 0.1% of people buy water in the form of 20 fl oz Dasani bottles.
