This is the point that matters most, and I would pay careful attention to and hone this instinct. It is the one that would truly reduce the "pain" of consuming your own efforts. Otherwise, I am not sure what to say, it is of course possible to write for different reasons and with different efforts and expectations, so I would not fret too much about how much you "care" about something over time, just how much it interests you to read your own points about it
