The London police have discovered that the best way to neuter demonstrations is not to move everyone on, or disperse troublemakers, but hold them close, cordon them into a diminishing space for hours and hours, as a sort of arbitrary al fresco arrest.

The encouragement I got from Campbell was a quick check and praise. Once the Space Beagle was launched on its mission, it seemed natural for it to breed additional thoughts.

Watching a whole cluster of friends, and my own mother, die over quite a short space of time convinced me that purely materialist 'explanations' for our mysterious human existence simply won't do - on an intellectual level.

It's true that I love to connect with my fans on the social networking sites, but I try not to go overboard, ever. I just give people a peek into my mind space, but never bombard them with my tweets.

The true exercise of freedom is - cannily and wisely and with grace - to move inside what space confines - and not seek to know what lies beyond and cannot be touched or tasted.

I actually don't invest in anything that is social, mobile, deals or ad networks simply because those are areas where there are so many players and so many other smart people in the space, I feel like I don't have a competitive advantage. So I tend to go after things that are e-commerce, like healthcare.

I didn't go to school for illustration. I did larger pieces, mostly drawings and paintings, and minored in video, but when I moved to N.Y.C., I didn't have a studio space anymore and downsized to my desk and started illustrating. I started a greeting card company and sold cards all over the city.

I had this job where I had to cold call people, and that was terrifying to me, and that was on a far different level than invading their space.
