You have kids growing up in some of the worst circumstances financially, living in some of the worst ghettos, and they succeed. They succeed because an adult figure, typically a mother, maybe a grandmother, nourishes the kid, supports the kid, protects the kid, encourages the kid to succeed. It's as if the environment never happened.

Self-control, openness, the ability to engage with others, to plan and to persist - these are the attributes that get people in the door and on the job, and lead to productive lives.

Some kids win the lottery at birth; far too many don't - and most people have a hard time catching up over the rest of their lives. Children raised in disadvantaged environments are not only much less likely to succeed in school or in society, but they are also much less likely to be healthy adults.

I remember sitting there on my father's couch or my mother's couch, listening to this lecture about how there were two groups and we had to be separated. We've come a long way from this kind of open racism. And I think it's wonderful.

I’m really excited by science and technology and the whole social media thing. I think it’s fascinating. But at the same time I’m wary of bureaucratic systems and managers.

I had to jump around in the arts for a while just to survive. I earned a little money here and there, playing the guitar at union meetings, functions. I sold some science-fiction stories. I knew there was absolutely no question of me not being connected with the arts, but I couldn't find any acting jobs.

Bodily discomfort and emotional fear and attachment make the dying uncomfortable and fearful. So, to help those dying people, I think modern medical science has a lot of facilities to reduce pain, or perhaps not to reduce pain, but not to experience pain.

The parts of physics that are exact are the parts of physics that are exact. The parts that are inexact are vastly greater. Sensible scientists don't waste their time pushing against doors that endlessly will not give. They are opportunistic and go where they can, but there are pitfalls in that.
