The three rules of improvisational theater are: 1) hear offers, 2) say “yes and” and 3) make your partner look good. Consider applying these simple rules in your daily interactions with coworkers and prospects. Listen, really listen, to what they are saying to hear others’ perspectives. Saying “yes and” leads to more positive opportunities than saying “yes but.” Finally, seek mutual benefit by making your partner/coworker/prospect look good because you’ll look good too.
