I’ve been facilitating CEO peer groups for fifteen years. The biggest factor in whether someone gets value from a group is vulnerability. Not performative vulnerability. The kind that costs you something to say out loud, the thing you'd rather not say because it makes you look uncertain, stuck, bored, scared, or wrong. The people who get the most from these groups aren't necessarily the ones with the biggest problems. They're the ones willing to let the room see the problem clearly enough to help.
