I always talk to young writers about when you make art in your room, you make art. And when you send it to New York and L.A., you have to be a professional. Of course, when you sell your book rights as an option for a movie, you have to be a professional about that.

I was writing full time after quitting a job as a high school English teacher, and I hadn't been able to sell anything, and my bank account was down to zero, and all of my friends were like 'What are you doing in the basement, when are you going to get a real job?', and my parents thought I'd completely lost it.

When I travel round the country, people can't place my accent; if there's someone in the audience, they'll be like, 'You're from Philadelphia', but everyone else will say, 'Where are you from, California?' I get England sometimes - bizarre!

The important thing for me as an artist is to keep going back to the page and doing what I do.

If you sequence a cancerous tumor, you should be able to tailor the therapy according to the root cause of the cancer. But it has taken so long to do the sequencing - which also requires time to prepare the samples and interpret the deluge of data that comes out - that the patients are already undergoing therapy by the process if over.

As a father, physician and nurse, I have a special place in my heart for children, and I know the brief window of opportunity we have to teach them simple lessons that can lead to a lifetime of good health.

I like working with my own body weight, and I just do the best job I can to be healthy and strong, both before and after a fight.

You can develop good judgement as you do the muscles of your body - by judicious, daily exercise.
