Tell me what you do...

This post from Duct Tape Marketing caught my eye as it ties into a previous discussion about bibliographic points-of-view. The post is about how to answer the question, "What do you do for a living" in a way that demonstrates your value. The example used is that of a doctor who tells people he, "help[s] people stay in their homes longer, go to one more grandaughter's [sic] wedding and attend their great, great grandson's Bar Mitzvah."

What would librarians say? We help students get A's on their papers? We enrich people's lives through reading? We create community and opportunity for everyone?
