Does reading make one a better writer?
Answer: Hmmmm, let me think… You would never jump into doing an open-heart surgery without having seen the procedure done a hundred times, right? The same happens with writing. All the theory and technique in the world is not going to help you if you don’t read. You have to know your environment, who are the players, how good are they and what people are reading. Anything else is pure bogus. Whoever tells you a writer doesn’t need to read to be a good writer is lying. Through. His. Teeth.
In the words of Samuel Johnson: “The greatest part of a writer’s time is spent in reading, in order to write; a man will turn over half a library to make one book.”
