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.

You get energy from other people, so hang out with energetic people.

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.

When I write, I love finding connections between ideas. When the connections are plentiful and strong, then I know it's a pretty good subject to write about.

There are a lot of ideas I've had that I originally was quite taken with, but over time, I lost steam. They stay on my list, but between me and you, I'm probably never going to do them.

I'm a writer and I also do a lot of professional speaking on risk taking and creativity as well.

There are interesting scientific and historical connections between these things that I just love.
