Audio books. But not software audio books (that sounds like torture). Listen to books on things that broaden your horizon. I listen to a lot of books on business and marketing even though my day to day job has nothing to do with that. I also listen to a lot of science fiction (old stuff and new) because it helps me appreciate where we have been and where we might strive to be as a thinking society.
