In my office, I like it quiet, so I can concentrate.

I travel internationally a lot and I have a hard time sleeping and staying awake normally after crossing multiple time zones, especially going east. I've tried light therapy but not found it too helpful.

Every day, I walk with my dog - summer, winter (it gets -20 F in Saint Paul), rain or shine. The nicer the day, of course, the longer the walk.

I started a funny book from the 1930s called The Code of the Woosters by P. G. Wodehouse. Wodehouse is a comic genius.

In my workshop, I like to have the TV on for background noise, but I only put on shows that you don't really need to watch in serial order; stuff you can glance up every once in a while and still know what's going on; for example, Cops reruns, Jeopardy!, and Forensic Files.

I'm really good at building things that shoot, hurl, or throw stuff.

Leonardo Da Vinci. Leonardo is arguably the world's most famous polymath. So many thoughts and so many different ideas!
