When I started writing, I learned the importance of also being a reader. Yes, a writer should read many books about the craft, but it's also important to read what others have written. Novels. How-To books, History, Home Decor, Travel and more. With our writer's mind, we note more in the books we read than others might.
Even if subconsciously, we take note of the way dialogue is presented, the method the author uses to bring a character to life, how the writer creates tension, the use of sensory details, the beauty of language and so much more. Perhaps, as writers, we are more aware of these kinds of things. If not, we should be.
If you're a mystery writer, should you only read mystery books? Should a romance writer immerse herself in nothing but romantic books? Should a travel writer ignore books that bring history to life? Of course not! No matter the genre we write, we should be wide read, expanding our horizons. We'll still pick up bits and pieces about our craft as we read.
More than once, when I have read an especially lovely sentence of paragraph, I stop and read it again to savor those beautiful words. My admiration for the writer goes up a notch or two, and I wish I could write like that.
Read not only books but newspapers and magazines, online newsletters. You learn, you enjoy, and you also pick up tips on how to write, even if that is not your original purpose. It's a very nice side-effect.
As writers, I hope we don't fall into the trap of watching tv and movies but seldom pick up a book to read. Some of each is fine. Find a balance that works for you. Be a writer and be a reader.
