Law of the Minimum: "The worst potential competition for any organism can come from its own kind. The species consumes necessities. Growth is limited by that necessity which is present in the least amount. The least favourable condition controls the rate of growth."
Frank HerbertWhen your opponent fears you, then's the moment when you give the fear its own rein, give it the time to work on him. Let it become terror. The terrified man fights himself. Eventually, he attacks in desperation. That is the most dangerous moment, but the terrified man can be trusted usually to make a fatal mistake. You are being trained here to detect these mistakes and use them.
