I begin each morning, I do every single morning exactly the same way, I begin each morning by doing my highest priority work first. I have a very clear priority list and I start from the highest priority work first. Before I even get to work, my day is already a success. I've already completed my most important work and can dedicate my day to helping others.

Apenas me despierto, a las 5:00 a. m., cuando voy a hacer deporte. Es lo primero que cojo cuando me despierto. No es la mejor práctica, pero sí desde tempranito.

When I’m working on a novel I type the initial draft first thing in the morning. Really: first thing. For preference, I have a cigarette ready-rolled and a coffee percolator loaded the night before; then I simply roll out of bed, fuel up and set to it. I believe the dreaming and imagining faculties are closely related, such that wreathed in night-time visions I find it possible to suspend disbelief in the very act of making stuff up.

I get to my desk (in a very small room at the top of the house) at about 10, and fiddle about with the height of the desk and the chair until I’m comfortable. I have a desk that I can raise or lower according to the state of my aching back. Sometimes I stand at it, and sometimes I have it high up to write at, and sometimes a bit lower to type.

If you get stuck, get away from your desk. Take a walk, take a bath, go to sleep, make a pie, draw, listen to ­music, meditate, exercise; whatever you do, don’t just stick there scowling at the problem. But don’t make telephone calls or go to a party; if you do, other people’s words will pour in where your lost words should be. Open a gap for them, create a space. Be patient.

Some writers claim to extrude a book at an even rate like toothpaste from a tube, or to build a story like a wall, so many feet per day. They sit at their desk and knock off their word quota, then frisk into their leisured evening, preening themselves. This is so alien to me that it might be another trade entirely.

Read Becoming a Writer, by Dorothea Brande. Then do what it says, including the tasks you think are impossible. You will particularly hate the advice to write first thing in the morning, but if you can manage it, it might well be the best thing you ever do for yourself. This book is about becoming a writer from the inside out. Many later advice manuals derive from it. You don’t really need any others, though if you want to boost your confidence, “how to” books seldom do any harm.
