A velocity of being

One of the great cruelties and great glories of creative work is the wild discrepancy of timelines between vision and execution. When we dream up a project, we invariably underestimate the amount of time and effort required to make it a reality. Rather than a cognitive bug, perhaps this is the supreme coping mechanism of the creative mind — if we could see clearly the toil ahead at the outset of any creative endeavor, we might be too dispirited to begin, too reluctant to gamble between the heroic and the foolish, too paralyzed to walk the long and tenuous tightrope of hope and fear by which any worthwhile destination is reached.
