Talk with your co-leader about the workshop. What do you think went well? What might you have done differently? Did you learn anything about your working relationship or how you lead an activity?
What has changed since you led the first workshop together? How does it feel to be finished with this extensive and deeply explorative program?
Thinking about the content of the workshop, what did you find most surprising about what you learned? Did the participants have any interesting reactions to the content? What would you like to learn more about?
You may want to have your own leaders' celebration as well, to acknowledge all that you have learned, the fun you have had, and your accomplishments.
