How might we...

  • How might we work more strategically?


Tracking my energy, focus, and mood every hour for a week will reveal natural rhythms that will help me optimize my day.


Every waking hour for seven days, track Energy, Focus, and Mood on a five point scale in a Google Spreadsheet. Set a calendar reminder to make sure I update the log. Carry around a small notebook when I’ll be away from digital devices.

After seven days, analyze the data and see if there are trends.


  • Did I successfully track for a week?
  • Are there usable patterns that emerge from the log?
    • Learnings

      I only managed to successfully track for 3.5 days. When I was home, it was fine (but still difficult). When I was traveling, it was impossible. Over the weekend, I went to a wedding that was far away, and that completely disrupted my logging.

      Still, one pattern was clear. I didn’t notice any cycles per se, but I did notice a strong, steady focus in the morning through lunch, then a gradual decrease in energy and focus, with no up-swing afterward.

      Possible future experiments: What activities could I do to create an up-swing after my post-lunch decline?


      Try to move all meetings (especially non-essential) to the afternoon, so I can reserve my mornings for focused work.



      1. I was inspired to try this experiment after reading this personal productivity article. For the most part, there was nothing new for me in this article, but I was intrigued by the section on tracking your biorhythms. I decided to basically try his experiment almost exactly — same frequency, same time period, same dimensions (i.e. Energy, Focus, Mood). The only difference is that I chose a five point scale rather than three. (I noticed he was using decimal points, which to me defeats the benefits of using a three point scale.)

        A few things I’ve noticed after a few days of tracking:

        • It’s challenging to answer these questions consistently. What’s the difference between Energy and Focus?
        • My mood doesn’t really fluctuate based on time of day.
        • I’m not noticing any cycles, and I’m not sure that any of these dimensions are strongly correlated to time of day (other than I have more energy in the beginning of the day than the end). All three dimensions also seem related to type of activity (e.g. exercise, meetings, writing, eating, etc.).
