Worklust

Where does worklust come from? How do you cultivate it? It's empirically true, in my experience, that no amount of thinking about something really gets anywhere until you get out your pencil and draw or write or pick up your guitar and play. My thoughts are pretty aimless and insubstantial and forgettable until I start writing, and then they just more or less spontaneously, without much help from me, take on an order and a shape and a trajectory and end up somewhere, often a place I couldn't have predicted. I often change my opinion about something in the process of arguing it out on paper. But that moment of getting out of my head and into the work feels like a very high threshold. I resist it with all the might of my formidably-built laziness. Lust doesn't require any effort at all, right? It's self-propelled. It's nearly unstoppable. Is worklust the right word for what makes some people produce so much? Or is it boring old discipline? Or is it occasional spasms of worklust that flare up in an otherwise boring schedule of disciplined, self-imposed, rationally-driven labor? Is worklust sustainable? How do you know the border between worklust and a pathological need to be recognized through your work? Or is that what it is? Huh?
