Our lives are lived in compartments, like panels in a cartoon strip.
Where you sit and when you leave and how you walked in--they are all markers, ways we space things out. Walking into the doctor's office or the principal's office or the parole office are physical acts that change our psyche.
Don't underestimate the power of having a customer walk into the dressing room or on stage or to the cash register. Don't forget that as soon as your audience walked into the conference room, they changed.
One way to change the story, then, is to change the markers. To move people from one spot to another when you want them to change their attitude (inside the movie theatre is very different from the popcorn-sales counter in the lobby).
I'm serious. Get up and move. Start fresh. [Bonus: the cartoon version!]
