My wife had trouble sleeping and discovered that not watching the TV (or any other kind of screen) in the evening made a positive difference. It has also helped me.
In the absence of television to amuse us, we turned to reading together. A good book is a very rewarding shared experience. Even better, we find, is reading aloud. Most nights, therefore, I read to my wife who sits on the sofa in front of the fire with her knitting. We started with my books. It's important for me to hear what I've written because it helps me eliminate clunky bits and also adjust the rhythm of the sentences. Reading to someone else also has the advantage of giving the opportunity for feedback, a valuable resource for any writer.
My wife is particularly good at picking up things that don't work. Awkward sentences, inadequate explanations, lack of detail, that kind of thing. There's a good adage when it comes to feedback:
If someone tells you that a piece doesn't work they're almost always right.
My wife is getting very good at helping me put things right.
Reading makes me a better writer. Writing makes me a better reader. I think it works for everyone.
In the days before television, books were the main source of entertainment and delight. There was a time, not so long ago, where not everyone could read and being read to was a valuable experience. Before that, storytelling was a purely verbal craft. I find that reading to my wife is wonderfully intimate and connective. It's a joyful and rewarding experience that nothing televisual could ever match.
My wife doesn't only have to listen to my books, though. We both delight in reading other things. Recently we've completed Peter Hoeg's The Susan Effect and Philip Pullman's Book of Dust. Currently we're getting on well with The Paranormal Policeman by D J Harrison (which is yet another one of mine).
As a writer, I can appreciate the craft that goes into a good book. One of the things that I particularly watch out for is the principle of Chekhov's Gun. This convention insists that something introduced into a story, such as a gun, must be used. Otherwise there is an element of dissatisfaction for the reader that they might not even be consciously aware of. In the Susan Effect there's an actual gun hanging on the wall which is taken down, examined and put carefully back onto position. My experience tells me to watch out for it later on and sure enough, there it is, popping up at the end in a very satisfying conclusion. A popgun, you might say if you were a humorous writer. I told my wife about Chekhov's gun. She's now on the lookout for more examples and says it makes reading (or listening) to stories even more enjoyable.
My editor once pointed out the way I was dangling items in front of my readers then never mentioning them ever again. She told me to cut it out, that it wasn't something a good writer ever did. I had to mention the Sternwood chauffeur in The Big Sleep (Marlowe never finds out who murdered him) but her justifiable reply was to the effect that if I ever became as proficient as Raymond Chandler then I could please myself. Until then, I'd be best advised to knuckle down and learn my craft.
That's what I'm doing and reading to my wife is a big part of that.
