Guest post by a once bookstore buyer, editor, and now prominent literary agent at Barry Goldblatt Literary.

You need an ivy league degree.
You need to be financially well off.
You need to have an upper middle class background, minimum, and the worldliness that life presumed.
I was a lower middle class kid from a mixed-race immigrant background, whose guidance counselor recommended I abandon my goals of either becoming an editor or a professor of English and take a look at a solid trade like sanitation management. Fortunately I have a personality that is a combination of old fashioned romanticism, which came from reading, and a deep sense of practicality, that comes from the way I grew up, being sickly, and poor enough to know I could not have everything I wanted. Then something wonderful happened: I stayed home one Saturday afternoon and watched T.V.
PBS on channel 13 was playing a marathon of The Power of Myth interview series by Bill Moyers with Joseph Campbell. It changed my life. It fulfilled my romantic idealism with a plan: Follow your bliss. So I thought about a way to get what I wanted, a life in words. I was working already, part-time, at a local B. Dalton Bookseller (#321), so that was my back-up plan: Be a full-time bookseller; rise in rank, and run a store. Then I lied.
