Books

I always have admired how authors write books, but now I respect them. I am writing a book for my passion project entitled: Two Views: The Pacific. I have just started chapter three and it is really hard to write. I can't see how authors do the for tons of books. I was hoping I could have it done within two weeks of starting, but I don't think that will happen. I am trying to have it start with the attack on Pearl Harbor and end with the battle of Okinawa, but just getting to Midway has taken two chapters. I will need some feed back as I go, so I will post what I have weekly and would appreciate any tips
