The analogy of hot coffee cups illustrates the concept of genius, working competency, and frustrations in relation to work. Genius is represented by a cup with a lid that holds heat and energy for a long time. Working competency is depicted by a cup that holds heat for a while but eventually cools off. Frustrations are symbolized by a cup with a hole in the bottom, where the coffee quickly drains out. The insight is that we should aim to do a significant portion of our work in a way that allows us to hold onto our energy for an extended period of time, making work feel effortless.
