As you adapt workshops to fit your resources and the needs of the group, take care to preserve the intent of a workshop and its purpose in the overall program.
Read each workshop at least several days before leading it. Get a feel for it, do a little extra research if your curiosity strikes, and follow your interests.
Preparing with your co-leader is very important. Each leader should read the workshop in advance and then together determine each co-leader's responsibilities. Immediately before the workshop, work together to set up the meeting space and ensure that the materials and equipment are available. Experience the Spiritual Preparation exercise together, if possible. At least, take a moment before participants arrive to go over what you'll do and to briefly share your expectations for the workshop.
