>I belong to a social group that does barbeque and goes for beers. What would group succeed at if I go "above an beyond"?

Well, I suppose this would mean that instead of just being a passive participant, you go out of your way to look for that cool new pub that your friends might enjoy, or a way to make the hamburgers more juicy. You'd take some pride in your ability to provide this value to the group and enjoy the improved social standing of being 'the one who really knows this stuff', and of course just enjoying a better culinary experience overall.
