Context:It was n't clear enough ; it did n't have all the right topics ; when I had the right topic , I did n't have straightforward , clear examples . I could go on and on . I felt that this was the sorriest excuse for a book that the world had seen and it was only the greater embarrassment of not delivering on my promise to the publishers that I would submit it that made me send the manuscript to them . Fortunately , in the six months since submission I have developed some perspective and have had unsolicited emails from people around the world saying how much they liked it .
Question Why did the narrator feel obligated to deliver the book ?
Answer:
Because they wanted to fulfill the promise to the publishers
