The first thing to learn in life, is how to govern. One is given primordial legacy VALUES, such as aversion to hunger, from which GOALS evolve, thus leading to STRATEGY development, which follows as a buffering intermediary from TACTICAL experience.
The second thing to learn in life, is how to MODIFY your VALUES. This is a meta game which applies the first learning, to then govern the premises of the first learning.
If you are successful at the first, and second, then life is complete. You can then focus on existing without purpose.
You may further then, engage with incomplete folks by applying the second learning, to EMULATE the values of others, at your leisure. This is the third thing to learn in life, which some call empathy.
