Since reading So good they can't ignore you by Cal Newport, I have been reflecting on what rare and valuable skills I should acquire/which field(s) I want to build passion in. As Cal explained so eloquently, people are not born with pre-existing passions, rather they develop passion as their skills improve, they gain experience and they get closer to mastery! My own limited experience concurs with his views, hence my identified passions are a result of previous time and effort, I was not born with them. I am not sure of the origin(s) but over time, a hunger to understand myself and reality has been steadily intensifying! At it's core, human perception of reality is entangled in the mechanics of our bodies which let us explore the world and simultaneously define the limits of our experience.
