I'm not so much interested in how difficult it is to track something as whether the data and its granularity maps out onto real change.

I went through periods of wanting to make changes in my life, and I thought it was all about figuring out a perfect system.

It turned out that the bigger problem was actually overthinking, and it was that overthinking itself which wanted more data and more methods.

In actuality, what helped was removing as much friction as possible. I have no data about my sleep except for the clear fact that I wake up earlier and spend almost no time rolling around my bed before getting out of it. I don't need either a watch or paper to tell me that.

I don't say that as a way of critiquing your methods, just wondering if you notice real, considerable change as a result, the kind that you don't need to minutely keep track of because it's so obvious.

Or to make it not personal, is there a known correlation between the popularity of fitness tracking devices and significant weight loss across populations?
