I strive to live a life of purpose. The purpose I chose is to contribute to society to the best of my abilities. As life is finite, I have limited time to pursue the act of contributing. Hence, I must I use my time wisely. In order to assess and improve my use of time, I must measure it.
I track all time commitments that matter to me, including those which are personal. The tool of choice is a digital calendar. On it, I prospectively block the time I intend to or must spend. Routinely, I analyse all these entries for frequency and duration to match their importance.
This allows me to measure and optimise the time I spend and effectively pursue the purpose I set in life.
