If I'm not in the dead heat of working on something, I can end up spending tons and tons of time on the Web, and I hate it. I feel the same shame I did in grad school when I was pretty much addicted to reruns of 'Star Trek: The Next Generation'. I wish someone would make the Web just go away. Just remove it from the earth.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
