Self-propelled… is that a good thing or a bad thing?
Bike messengers and writers have a lot in common, I discover. In both activities, every forward motion is self-propelled. If you stop trying, you will shortly stop moving, and stop earning. Both activities involve gathering things and dispersing them. Bike messengers are given specific destinations. Sometimes writers have specific destinations in mind, too. And sometimes they don’t. In both cases, however, how you get there is for you to figure out. — Thomas Beller, NYTimes
