Every observation of a person potentially tells you something valuable about how they operate. As I explained earlier, I call these observations "dots." A dot is a piece of data that's paired with your inference about what it means--a judgment about what someone might have decided, said, or thought. Most of the time we make these inferences and judgments implicitly and keep them to ourselves, but I believe that if they are collected systematically and put into perspective over time, they can be extremely valuable when it's time to step back and synthesize the picture of a person.
