For the second straight year, I've recorded my activities in six categories: Daily, Health, Music, Social, Work, and Education (each represented by a different color in the graph above). I started this for the purpose of self-accountability during grad school, when there just aren't enough hours in the day. This data lives in a giant Excel spreadsheet that I update daily.
