By doing this, you will begin to understand how the machinery underlying any “another one of those” works and develop a mental map for dealing with it. As your understanding of these relationships grows, the essentials stand out from the blizzard of things coming at you; you will notice which “one of those” you are facing and instinctually apply the right principles to help you through it. Reality, in turn, will send you loud signals about how well your principles are working by rewarding or punishing you, so you will learn to fine-tune them accordingly.
