I have a little office in my house and it is an absolute pigsty but I know exactly where everything is and there are little things stuck all over the walls, and papers in in-trays and files I have saved on my computer and playlists I have made on my iTunes - things that take me to a place that I think is appropriate.

We're all flawed heroes. Responsibility is power. Take responsibility for the consequences of your actions, and the world is yours. Everything is a choice.

I think that is so interesting. It is le Carré. There must be so much of him when he was younger. He's an interesting character. I don't want to say the word "passive" because there is something very active about the way he is passive, if that makes any sense: the nature of his watching and his listening is active. It is always so alive because he is, essentially, a spy.

I definitely go through periods where I'm in a particular mood, or there's a consistent imaginative context that I feel I'm in, and I'm drawn to certain things. I can sometimes feel it when I'm moving away from something that I was once interested in - an idea or an exploration of particular relationships. I go, 'Well, I think I've done that and I don't want to do it again.'

Nurture your own confidence and make it real; don't pretend to be someone you're not.

I am so profoundly aware of my lack of skill to make any material difference. I am not a doctor. I can't influence foreign policy. I can't build schools. I can't chemically engineer the protein paste that helps people with acute malnutrition. But I can talk about it, and so can you.

One of the great flaws that we all share is that we think everyone else is cooler, everyone else is sexier; everyone else has all the answers. That was me too.
