Get into the habit of really seeing things, observing tiny detail, the nuance of all you encounter, as if you were a child seeing it for the first time. The veins in a leaf, the actual hue and texture of blood, the taste of fresh coffee. Don't write about your memory of these things - which will be laden with clichés - go and experience them first hand. (Except the blood; wait for that to come to you.)
Writers don’t stumble blindly through life; everything and anything should fascinate you. Especially people. Describe their behaviour in your mind; assume their motives; listen to them, watch them, study them. What gives them away? Where does that nervous twitch come from? Imagine what their worst fear might be, the terror they’ll never speak of? Who was their first love fifty years ago? What events have shaped them? What thought sends them to sleep each night? What's the one thing they'll never tell anybody?
There are no days off, I’m afraid. You are always writing.
