To track how I use my time the need for categories came up. It got involved.
Asking myself what I am trying to learn got me to the two categories that matter most to my enjoyment of life: The ratio of joy to pleasure in my life.
As I indulge more in pleasure, I have less time for joy. As I walk away from joy, I walk towards eventual sadness and tiredness.
This one ratio is an unerring canary for how I am feeling, and will feel in the future.
