I was seated in the office of the vice-president of sales of a company I’d been consulting with for several years. ①He was interviewing someone for the position of regional sales director and asked me to listen in. The man interviewed was an experienced, successful salesman. Still, it was an important career meeting for him, and ② he was nervous. His response to the pressure of the interview was to talk too much. ③ He felt uncomfortable and was attempting to fill the uncertainty of the moment with sound. While trying to make a good impression, ④ he presented himself poorly. A little conscious breathing would have enabled ⑤ him to feel better about himself and allowed him to be more calm and clear.
