I find doing the writing this way, I keep the story very much alive in my mind, every character, the theme, the sub-plots as so on - all of it. Because of that, I can enrich the story and improve the plot and pacing.
Now I am just about to save it. This I do every night as one terrible time I clicked on a virus in my live mail and my computer crashed. It was a Trojan Horse - one of the horrible ones - no mercy. Awful feeling. Now the usb's come out every night.
Good night have a lovely night or day. Good luck with your writing or whatever you are doing.
