I came across this a few years ago, it’s very cool. I enjoy the quantified self thing but personally struggle to do anything useful with the data I collect. It’s always interesting comparing time spans but other than that nothing actionable. Do any quantified self people have any advice on how to utilise data for positive effect? Edit: after reading the full thing something that jumped out to me was summer/winter comparisons. If you have the freedom to work anywhere, chasing sun seems like it could have quite a positive impact on your general health and well-being.
