This is what I learned from this book: 
 If you sneeze on a piece of paper, then you become famous, then you die, 
 or 
 If you sneeze on a piece of paper, then you die, then you become famous, 
 that piece of paper becomes a treasure!...or perhaps a national treasure! 
 Not sure how many pages the Editor/Publisher wasted in this book to show us, the readers, some photos of hand written notes and scraps....as if we, the readers, can recognize Hemingway's hand writing when we see it!lol 
 ....as if the Editor/Publisher himself doesn't believe that what is written in this book is by Hemingway and was afraid that such doubts will spread to the readers, so he/they made extra efforts to prove it by including photos of what I think was brainstorming notes. 
 Hemingway wrote what in this book or he did not, does not really matter. 
 Hemingway did not approve what is written and published in this book, so the credibility, at least to me, is lost. 
 ....and just few lines from this book caught my attention. 
 This is one of the books I felt excited when I found and were very disappointed when I finished :(
