Well, ya. There are those 'old timers' that say the same thing every time....and its usually long winded. I kind of giggle cause I can see the 'oh no here we go' faces and people pushing back in their seats. Fortunately there are usually just a couple of those. And meetings are also for newcomers (not exclusively of course) so there is a lot of repetition. I think the idea is get out of the observational, listening, newcomer mode and into the action, helping others mode. That's kind of where the magic happens. I don't share much in the meetings either. Actually, pretty much never. I'm a one on one kinda person.
Try different meetings. But just cause you don't like speaking (which I get) doesn't mean others don't love hearing themselves talk
