It's like that subway map. It all looks orderly, and like everything is spaced neatly and falls into place. But they just drew the map that way, because it's easier to read. The stations really don't line up like so many slices of blueberry pie. They're cobbled together, a bit, with blood and sweat and welded rails, and the whole system holds together in ways you could never map.
So you can't look around you in the subway car and decide that everyone else either knows where they're going, or knows not to care. You have to realize that they're like subway maps, too. They may seem as predictible as station names, but in fact they've all got little ugly twists and secret gardens and turns into corners beside quaint Italian restaurants.
You can spend a lot of time obsessing about directions. You can lament that you don't seem to have the monthly pass, or that the neighborhood from which you must catch the train is a lot further from where you want to go then you wish were the case. You can even point to the holes in your pocket from using token after token, just to find that you're still stuck on the light rail on the outer rim circling the inner places where all the action takes place.
But sometimes you just gotta take out that map, and fix upon a destination, and just ride without all those inner voices telling you about the problems with railroading. You're in it for the ride, not the exit turnstile. You scan the map like it's a lot more colorful and a lot more interesting than you ever imagined,if you just look carefully at the colors.
You plot a point, and ride there,when you can. You may have to hop off the train to earn your tokens, sometimes. Someday you may even earn a monthly pass. Until that day, you ride as if you have a destination, and just keep working the map.
