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 felt it was the best book the world had seenBecause they had all the right topicsBecause they wanted to fulfill the promise to the publishersBecause they felt it was the sorriest book the world had seen
