" Once you’ve identified these goals, list for each the two or three most important activities that help you satisfy the goal. These activities should be specific enough to allow you to clearly picture doing them. On the other hand, they should be general enough that they’re not tied to a onetime outcome. For example, “do better research” is too general (what does it look like to be “doing better research”?), while “finish paper on broadcast lower bounds in time for upcoming conference submission” is too specific (it’s a onetime outcome). A good activity in this context would be something like: “regularly read and understand the cutting-edge results in my field. "
