Thomas Edison said “Genius is 1% inspiration and 99% perspiration.”  The same could be said for writing I think.  I am slogging through what I hope will be my last edit.  I have the wonderful editing my sister-in-law, who is a copywriter in real life, did for me.  It is amazing to me how many corrections she found when others missed them.  I am also working on the book from the perspective of my writing partner, rethinking every concept for validity.  And on my own, I am trying to look at what can be cut, or smoothed or re-paragraphed to increase the ease of the reader and their ability to interact with my writing.  So to paraphrase Edison, I have come to believe, “A Book is 10% creativity and 90% grammar checking and hard work!”
