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 have a large standalone workshop on the back of my property where I prototype and build stuff. It's bright, roomy, and has a giant door so it's easy to bring projects in or out.

My home office and workshop are on an overlook on the only deep river gorge on the entire length of the Mississippi River.

I've seen Leonardo Da Vinci notebooks which are filled with tiny, messy scrawls written in mirror image across the page. I'd love to know how he kept all his projects going at once.

I think it's important to associate with positive, upbeat people.

In my home office, I built a custom sit-stand desk to which I connected a big, kidney shaped glass top which I got for cheap at Ikea. Kidney-shaped desk tops are, I think, the most efficient of all possible desk shapes.

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.
