The author has done a great job of finding real-life examples. What balance of new activities and familiar favorites is the most fulfilling? When you cook a bread from a recipe, when you knit a sweater from a pattern, when you put a sharp edge on a piece of flint by executing a precise sequence of strikes with the end of an antler- a key step in making fine stone tools, you are following an algorithm. The whole business, whether it's the relative simplicity of the 37% rule or the mind-twisting possibilities of game theory, is both potentially practical and highly enjoyable as presented here. If your definition of “productivity” is efficient time management, you only need to know one thing –  the task order is irrelevant. If a lower priority task is blocking a higher priority one, it must assume the priority level of the task it is blocking. Thinking about scheduling algorithmically is helpful because it provides a rational framework for setting priorities.
