Have you ever been sitting in a bar, an airport, a library, or browsing in a bookstore when a stranger tried to start a conversation with you? Did you feel awkward or on your guard? The conversation itself is not necessarily what caused the discomfort. The discomfort was induced because you didn’t know when or if it would end. For this reason, the first step in the process of developing great rapport and having great conversations is letting the other person know that there is an end in sight, and it is really close.

Establishing artificial time constraints is one of the 10 techniques for building quick rapport with anyone by Robin Dreeke, the head of the FBI’s Counterintelligence Behavioral Analysis Program. 

Interesting.
