I kept always two books in my pocket, one to read, one to write in.Robert Louis Stevenson
I can’t stress how important it is to read and to take notes. These are probably two of the most important things a writer can do. Regular reading exercises the storytelling muscles of your imagination. It keeps your head in fiction mode and consciously or not, you will learn from what you read. You will see how to affect the reader, build suspense and craft a clean and effective sentence; you will also be able to identify those parts of the text that don’t work for you, and interrogate why that is.
Note-taking is just as essential. As you go about your day, jot down interesting turns of phrase that you hear, plot ideas, character or place descriptions. Whether you use a paper notebook or a phone app, get it all down somewhere and you will find this serves a duel purpose. Firstly, you will be able to mine these notes for inspiration and detail; secondly, the act of translating what you see and hear into words will keep the writing part of your brain active and engaged, like an engine constantly ticking over, so that when you sit at your desk to write, you won’t be starting cold.
