One cannot overemphasize the importance of observation and a full assessment — the failure to do so leads to some of the greatest mistakes, not only in war but also in business and government. A full assessment is critical. To properly manage any business situation, you need to perform a full and complete assessment of it. In business, you have to understand your competitors, their distribution, their economics, their innovations, and their strengths and weaknesses. You also need to understand customers and their changing preferences, along with your own costs, your people and their skills.

The artistic process seems to be mythologized quite a lot into something far greater than it actually is. It is just hard labor. […] As anyone who actually writes knows, if you sit down and are prepared, then the ideas come. There’s a lot of different ways people explain that, but, you know, I find that if I sit down and I prepare myself, generally things get done.

And now, what are those of us who are elected public officials supposed to do? We call ourselves "public servants" but I'll tell you this: We as public servants must set an example for the rest of the nation. It is hypocritical for the public official to admonish and exhort the people to uphold the common good if we are derelict in upholding the common good. More is required -- More is required of public officials than slogans and handshakes and press releases. More is required. We must hold ourselves strictly accountable. We must provide the people with a vision of the future.

Nothing comes to my desk that is perfectly solvable. … Otherwise, someone else would have solved it. So you wind up dealing with probabilities. Any given decision you make you'll wind up with a 30 to 40 percent chance that it isn't going to work. You have to own that and feel comfortable with the way you made the decision. You can't be paralyzed by the fact that it might not work out.

Writing fiction is not “self-­expression” or “therapy”. Novels are for readers, and writing them means the crafty, patient, selfless construction of effects. I think of my novels as being something like fairground rides: my job is to strap the reader into their car at the start of chapter one, then trundle and whizz them through scenes and surprises, on a carefully planned route, and at a finely engineered pace.

Don’t panic. Midway through writing a novel, I have regularly experienced moments of bowel-curdling terror, as I contemplate the drivel on the screen before me and see beyond it, in quick succession, the derisive reviews, the friends’ embarrassment, the failing career, the dwindling income, the repossessed house, the divorce . . . Working doggedly on through crises like these, however, has always got me there in the end. Leaving the desk for a while can help. Talking the problem through can help me recall what I was trying to achieve before I got stuck. Going for a long walk almost always gets me thinking about my manuscript in a slightly new way.

I'm writing with a clear lesbian agenda in the novels. It's right there at the heart of the books.
