I find the attempt to find things out, which scientists are possessed by, to be as human as breathing, or feeding, or sex. And so the science has to be in the novels as science and not just as metaphors.
Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting.
A lizard is a perfect pet for a model. They only need feeding once a fortnight. And I'm always travelling, so it's perfect. If I had a dog, it would drop dead of starvation.
If you live in Port Arthur, Texas, and you don't have any food to feed your family for dinner tonight, global warming is not the most important issue; getting a job and feeding your family is.
Whenever I feel mom-guilt, or I feel pressure to be a better mom - to cook salmon on a bed of quinoa for my kids - I just think to myself, 'I... have... suffered... enough.' And then I feel fine about feeding my toddler a bag of chips for dinner.
When I sat down to write 'Rules of Civility,' I didn't write it for anybody but myself. I wasn't trying to make my mark or make money. I wasn't anxious about feeding my kids or whether my father would be proud of me.
Getting up at four in the morning to tend the farm while the world is quiet - feeding animals, mucking stalls, gathering eggs, filling water troughs, checking fences, letting animals out into the field - is a high point to my day.
Probably the hardest question I get asked is, 'How do I choose between passion and practicality?' I can't answer that. I had to do both. I was passionate about pursuing a career in financial services. But I was also passionate about feeding my child.
