I had passed through the entire British education system studying literature, culminating in three years of reading English at Oxford, and they'd never told me about something as basic as the importance of point of view in fiction!
If a spectator with a philosophical mind, somebody accustomed to reading books, gets the same kind of information in a movie, he might not fully understand it.
I do believe that reading can help you understand what you're writing and see what others are doing. But sometimes the desire for more information can act as an inhibitor.
My reading is extremely eclectic. Lately I've been teaching myself computer graphics, so I'm reading a lot about that. I read books of trivia, of facts.
Poetry seems to sink into us the way prose doesn't. I can still quote verses I learned when I was very young, but I have trouble remembering one line of a novel I just finished reading.
Write a lot. And finish what you write. Don't join writer's clubs and go sit around having coffee reading pieces of your manuscript to people. Write it. Finish it. I set those rules up years ago, and nothing's changed.
