Concentrate on sharpening your memory and peeling your sensibility. Cut every page you write by at least one third. Stop constructing those piffling little similes of yours. Work out what it is you want to say. Then say it in the most direct and vigorous way you can. Eat meat. Drink blook. Give up your social life and don't think you can have friends. Rise in the quiet hours of the night and prick your fingertips and use the blood for ink
 that will cure you of persiflage!
Hilary Mantel, Giving Up the Ghost
