Compounding skills improve your life exponentially
We have an intuition about the benefit we get from learning a skill. Learning how to remember information better is more beneficial than learning how to recognise trees using leaves. What is the cause of the greater benefit? And what are some examples of more and less beneficial skills? I determine the utility of a skill as a sum of how much fun it is, how valuable it is to other people and how large is the context in which I can apply the skill.
