I also feel like it gets to a roundaboutway of 'proving' things people already know. More sleep is nicer, unless it's so long it's bc you're sick. Drinking more means more dancing. Days when you sit all day working are less fun than walking around with friends (and, of course, not working then)
I feel like keeping a rough journal and manually revisiting would be more helpful than quantifying and correlating. But financial tracking can be useful, to a smaller degree, and tracking mood changes over big life changes can be valuable I guess. Otherwise, does feel vanity
True, but it seems like it would be nice to know where to draw the lines. More sleep is good, but how much more? Etc.
Sometimes, it feels like there's so much going on that it's hard to know if it was the sleep, the diet, the events, or something else. That's where the data might be nice.
