Pin Pricks
Great day? Watch someone come along and spoil it.
Process: The host invites members of the conference to suggest some of the small (or not so small) things that upset them. They are asked to imagine how any these things might turn a good day, bad. Once the list is assembled the conference see how it is not the event, but our response which determines the outcome. For example, depending on our mood, a person driving too fast might be a road-raged loon, or simply someone in a hurry.
Outcome: If we are careful to choose our response to an event we can control our "state" and not allow little pricks to bust our balloon. A powerful tool delivered with great fun.
