Think Fast, Think Slow
Sometimes we need to react fast, automatically. For example, as we see a large truck speeding towards us as we are standing in the edge of the street waiting for a traffic light to change. Or, as we observe the subtle cues of a very dissatisfied client. And, at a different time, we may find ourselves totally engrossed in the deep work1 of a seemingly intractable problem. And, then our thoughts and actions need to proceed at a slower pace.
