We have a group leader who usually brings topics of discussions and/or list of activities, but we're all mostly regulars so we'll have one topic and then just talk the rest of the time. But we sometimes plan our public speaking practice where the previous meeting we'll invite people to take up the challenge of giving a little speech on anything they want in order to practice their speech, public speaking, and controlling their fears in front of a group. Also we'll sometimes break into smaller groups if we have too many. We'll have activities where we make lists on a subject and then share about experiences and discuss. There's a lot of different things that can be done to keep a session rolling smoothly.
