I've been doing it in bits for a few years, mostly because I'm a sucker for interesting-looking graphs of data, but imo it's a mixed blessing. I've definitely found interesting trends, but measuring is also something I'm actively conscious of, and, as is often the case, it's hard to measure things without the very fact of measurement changing them.

I find myself struggling to avoid falling into the trap of doing or avoiding-to-do things specifically so that they'll show up in the analytics in a certain way that looks nice, which feels like a weird "teaching to the test" but applied to my actual life. Some things I've since stopped tracking because I really disliked the meta-ness of it all.
