Writing a book

Alot of people think that writing a book is like writing a essay but I'm going to tell you right here, Its not by far. I've been working on a book for a year now and I'm not even done with half of it yet. Writing a book takes time and creativity, and maybe more but those are the most important parts. I've given up one countless books, but always come back and write a chapter or two, but I read back first  because I've forgotten what happened! My advice is never stop writing a book always keep on writing.
