This is great. I get lost in books. I see and feel and smell the books.
It sucks when I am editing.
One of the tools and methods I use to help me is Text to Voice. Computer generated speech has gotten really good.
All I do is save the document as a .PDF, open the PDF and select VIEW menu, click on READ OUT LOUD.
This will allow you to listen to the book. I usually follow along in the MSWord doc. I am amazed how many times I repeat words like "and and" or use the word "Though" when I wanted "Through".
Doing this will also keep you focused. Put on headphones and roll.
