Perhaps along with thinking about whether it is worth it or not, maybe thinking about what you can do in support of a volunteer organization you choose to belong to. I was working in my clan tent during a festival and a lad came up and said he was looking for his clan, but they weren't there. He was a bit upset about it. My collegue asked if he was a member of the clan and he said no. She then said, well, perhaps the clan is off looking for you?

Another similar situation came up at another festival with a lad looking for his clan. He also was upset there was no presence for his clan--to which the same collegue replied, "well, you're here aren't you?".
