As creative people, we should be really conscious of being of service in our work, being as generous as we can.
It should be said upfront that I totally dig people who work in bookstores and libraries. They love books, and I love books, and that is all I really need to know. If they are friendly to me, then we are clearly soul mates.
I always tell people this when they're looking for an agent - they should love your work. You are entitled to work with someone who believes in you. Why do business with someone who is ambivalent about you and your art?
