That's a central part of philosophy, of ethics. What do I owe to strangers? What do I owe to my family? What is it to live a good life? Those are questions which we face as individuals.

Sometimes we know the best thing to do, but fail to do it. New year's resolutions are often like that. We make resolutions because we know it would be better for us to lose weight, or get fit, or spend more time with our children. The problem is that a resolution is generally easier to break than it is to keep.

I'm not overly alarmist about it, but I do think there are some worrying signs, like the growing accumulation of wealth by a very small proportion of the population, plus elections in the US are much more dominated by money than anywhere else calling itself a democracy.

Tacked above my desk are photos of artists I admire - Hopper, Sargent, Twain - and postcards from beloved bookstores where I've spent all my time and money - Tattered Cover, Elliot Bay, Harvard Bookstore.

I think it's a very old and deep-seated double standard that holds that when a man writes about family and feelings, it's literature with a capital L, but when a woman considers the same topics, it's romance, or a beach book - in short, it's something unworthy of a serious critic's attention.

I thought back to my middle-school experience of having slumber parties and watching Romeo + Juliet and staring at Leo and thinking about my first kiss and what I wanted it to be like. And when you have your first real love, it's an epiphany, you know? It's like a whole new world.

I like playing off strong actors, whether it's Benedict Cumberbatch or Dominic Cooper. Also I'm a hopeless romantic, so I'm fascinated by relationships.
