I'm Asian-American, and I was the only Chinese girl growing up in a white school in San Diego. So I understood what it was like to be different, to always want to fit in and never feel like you ever could.

I have minor characters who are Asian-American, and I've been using them throughout my career, but they've never taken center stage, they've never been really powerful, they've never expressed some of the experiences I had growing up in the U.S. Johnny Tam is the first one.

My brother often complains to me about the 'angry Asian male' in the United States. As a female, I haven't encountered this, but Asian-American men are angry. They're angry because, for so many years, they've been neglected as sex symbols. Asian women have it much easier, I think; we're accepted into various circles.

Because I never plan anything out ahead of time, I'm always in the process of learning about my characters. Without a biographical sketch to guide me, I discover things about my heroines as the stories unfold. Only in 'Body Double' did I discover that Maura's mother was a serial killer.

What if I told you every single person in America - every single person on Earth - is African? With a small scrape of cells from the inside of anyone's cheek, the science of genetics can even prove it.

To me, the most shocking thing about grit is how little we know, how little science knows, about building it. Every day, parents and teachers ask me, 'How do I build grit in kids? What do I do to teach kids a solid work ethic? How do I keep them motivated for the long run?' The honest answer is, I don't know.

Carl von Rokitansky is one of the founders of scientific medicine and systematized it, looking at what the clinical symptoms mean. The medicine we practice today, which is infinitely more sophisticated, is Rokitansky's medicine.

One of the things that all religions have is a narrative of doomsday. There has to be some kind of overarching fear of the future. If there wasn't, none of the religions could invoke this important thing - that science has no evidence of, by the way - called free will.
