It takes me out of my own limited, chosen world.

I do a lot of writing and note-taking on trips: in airports, on airplanes, on trains. I recommend taking public transportation whenever possible. There are many good reasons to do this (one’s carbon footprint, safety, productive use of time, support of public transportation, etc.), but for a writer, here are two in particular: 1) you will write a good deal more waiting for a bus or sitting on a train than you will driving a car, or as a passenger in a car; and (2) you will be thrown in with strangers—people not of your choosing. Although I pass strangers when I’m walking on a city street, it is only while traveling on public transportation that I sit thigh to thigh with them on a subway, stare at the back of their heads waiting in line, and overhear sometimes extended conversations. It takes me out of my own limited, chosen world. Sometimes I have good, enlightening conversations with them.
