(This one seems complex at first but once everyone gets it, it's a very fun and powerful activity.)
Clients take six strips of paper each. Write three Negative Messages or beliefs on three of the paper strips; i.e. You're dumb, you're ugly, etc. Write three Powerful, Positive Responses to the messages on the other three paper strips; i.e. I have confidence in my abilities. I'm proud of the way I look.
Form two rows of three standing opposite each other. Let participants choose if they want to be in the "Good" row or the "Evil" row. A participant gives one of his Negative Messages to each person in the "Evil" row. He gives the corresponding Powerful, Positive Response paper to the person in the "Good" row that is facing the "Evil" side. The participant stands between the first pair as they read the messages on the sheets and try to influence the participant using ad lib sentences. The "Evil" person extends her arm out to block the participant from passing.
e.g. Evil: "You're really dumb. You are always so slow. Why don't you ever understand anything?" Good: "I'm proud of my abilities. I may not be perfect, but I'm exactly who I need to be." Participant listens to the two sides and finally chooses the "Good" side by repeating the Powerful Positive Response and pushing past the "Evil" person's arm block. Participant repeats process with next pair until finished with all three pairs. Repeat for each person.
