If you went down that route, wouldn’t you include “enjoyment” as a goal, as a way your life would be “better”, and so that would get taken into account in your analysis?
You mean like attending a class every week and practicing daily?
As another example, I also read fiction. I don't set goals like "I want to read X number of chapters this week" or "I want to read for X hours this week", nor do I track how much time I spend on it. It is purely for enjoyment, it doesn't matter.
