 As a facilitator it's really important to not be rigid in the way you do things. So remember there's no one tool or technique or recipe that will always work every time with every group. Expect that things are going to go wrong in your meeting. Expect that there might be a troublemaker in the room. Expect that your equipment might not work. Expect that you're going to be tired and expect that a conversation could be completely derailed. You can be prepared and you should plan ahead but you always need to be ready to adapt to what's happening in the moment. Be flexible and be present.
