I think this topic has been done to death, but just in case some of you were wondering why I wouldn’t want to represent a book that was certainly of publishable quality, or by most standards a “good” or “very good” book, here is a very short analogy.
You are at a bookstore. You pick up a book. You like it. It seems like a good book. It seems like a book that deserved to be published, at least in your opinion.
But today, you are only buying one book. You have a great many books at home already and you love them all. You have very limited shelf space and you don’t want to get rid of the books that you do love to make room for a book that you might not love as much. And so today, you will only bring home one, because that is what you have room for. Tomorrow, you might have more room. Perhaps you will have a new bookcase even. But today, there will only be one.
So you put back the book you really like, a little wistfully, because you know someone else will probably take it home, and you pick up the next book on the shelf. And you keep going, until you find the one that you love.
