I've been told by plenty of authors and blogs that once you write a book and get it published, leave it alone. I was flipping through my book today and noticed thee words repeated in two sentence right after the other one.
Yes I can go and fix it and reprint it, but the more I keep changing the words with adding or deleting, it will be a whole different story. This book is done and I will not make any changes at all. (unless it is a must)
