Well, I've been a big fan of comic books since I was a little kid. In fact, I used to write and draw my own comic books when I was on the old Lost in Space series.

I had my guitar at the set of 'Lost in Space' every day. I was the only one in the cast who had a stereo in his dressing room. So while I was in school or when I was in there working with Dr. Smith and the robot, half the rest of the cast was in my trailer listening to their records that they would bring.

And of course, I absolutely loved making Lost in Space as a kid.

I started playing the guitar when we started filming the pilot to 'Lost in Space,' which was way back in December of 1964, and there's a little bit in the pilot that was used in the first season where Will Robinson is sitting around some bad foam rubber rock playing and singing 'Greensleeves.'

It's a failure of imagination if you can only write what you know - we have to be able to imagine different worlds.

There is a common and persistent belief out there that entrepreneurship is about creativity - that it's about having a great idea. But it's not, really. Entrepreneurship isn't about creativity. It's about organization-building - which, in turn, is about people.

Writing poetry is such an intense experience that it helps to start the process in a casual or wayward frame of mind.

Then there was Clark Ashton Smith, who wrote for Weird Tales and who had a wild imagination. He wasn't a very talented writer, but his imagination was wonderful.
