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. You can kick-start a whole book with some little writing exercise.
I can't think of any male politician who magnetizes love and hate - mainly hate - the way [Margaret Thatcher] did.
What is it we are hating? It goes beyond politics. I suppose that my fascination with [Margaret Thatcher] is not just with her political record but with her as a phenomenon.
