An interesting perspective is to look at oneself as a quantifiable self, not merely a glorified qualitative being that cannot be pinned down to a few measurable data. Data driven being. A monitorable entity in terms of numbers. Like we monitor a country’s economic growth in terms of GDP etc.
The obvious assumption is that the quantitative goals are set before hand and the progress monitored in terms of the goals. Alternatively benchmarks are set in terms of desirable quantities and the progress monitored. A third thing is don’t monitor in terms of preset goals but monitor post facto and take corrective action wherever warranted.
All this for what? Everything traces back to making best of life and derive maximum happiness out of it so as to lead a meaningful life .Ha, ha. Without doing all this if we can lead a life of happiness we don’t need to carry all that metrics with us!
