So it didnt end up working too well seeing that the latest data is from 4 years ago.

I wonder how much time you spend daily on tracking things / data entry

The takeaways at the very bottom of the page are valuable: > Overall, having spent a significant amount of time building this project, scaling it up to the size it’s at now, as well as analysing the data, the main conclusion is that it is not worth building your own solution, and investing this much time. When I first started building this project 3 years ago, I expected to learn way more surprising and interesting facts. There were some, and it’s super interesting to look through those graphs, however retrospectively, it did not justify the hundreds of hours I invested in this project. The whole "quantified self" movement might be more about OCD and perfectionism than anything else. /edit: quantified, not qualified

In my experience, tracking objective things like "nutrition" and "sleep hours" is immensely useful to reflect on what went wrong, and tracking subjective things like "mood" or "stress" is useless given hedonic adaptation or heavy swings that make problems obvious, and not need tracking. What's key is be able to visualize metrics easily on the data and frictionless data entry, I've got a decent setup with iPhone Action + Obsidian + QuickAdd scripts on Obsidian Sync (mobile + laptop). for visualization I use Obsidian Bases and Obsidian notes that run Dataview code blocks and Chart.js, couldn't be happier. I could track things that are not interesting to reflect on like vitamin D supplementation for accountability but I've never bothered, especially if it's taken ~daily.

Taking “Know thyself” to a whole new level. I’d love to have these stats on me, if it could be done by inference, rather than conscious effort.

Yeah, we've all put our whole lives into a single database. It's called the United States Government.

I get that everyone wants to be cynical about this, but you really can't deny that both the visualization and sheer scale of data is impressive. The way the "my life in weeks" is done is also very cool, I'll be stealing that for myself.

An interesting experiment, I think I'm too uncomfortable leaking data I don't yet know why someone would curate to me free of charge until I knew. If there was a FOSS suite like Home Assistant that would do a few of those things I might try it out, especially the weather (I would add air quality) correlation to mood and other subjective states.

This might sound harsh but for someone who is keen on investing time to track so many things, you should invest some time in learning how to make better visualizations. A few tweaks here and there would really improve what you have.

This was far more interesting than I first thought it would be when clicking the link. In particular, the place/time and life events and such being presented this way told a story and was fun.

tomovo

Stop bragging, mine fits into a csv file.

Related to this, I highly recommend anyone to install github.com/ActivityWatch/activitywatch, it's an amazing tool to keep track of your computer use completely locally. I think there are lots of possibilities with data analysis/AI aimed to improved one self's life

Hope they made backups :)

I had an idea similar to this where you could add information about yourself and answer daily questions and get paid by companies who access this data. This could be an ethical way to share information benefitting all parties.

I thought you created a database from scratch, got me excited! (I’m a db guy)

A simple back of the envelope calculation shows that Felix causes between 70 and 110 tonnes of CO2 emissions per year just from flying. Paris accord says 1.5t per person per year, from all activities, Felix's flying alonre is ~10-15x current European yearly per person emissions and ~50-75x those compatible with +1.5C.

Tacite

I'd like to make the same but with Owntracks instead of Swarm and ActivityWatch instead of RescueTime.

The step count in NYC stands out like One World Trade Center compared to the rest of the building when looking at the skyline ;-)

sbcorvus

This looks like it requires a heavy amount of discipline to track everything consistently over time. How do you build that into your daily routine?

No need to spy on him, he publishes everything.
