Sometimes writing is running downhill, your fingers jerking behind you on the keyboard the way your legs do when they can’t quite keep up with gravity.

The line likens an ideal writing session to the bodily sensation of running downhill: exhilarating, slightly out of control, and propelled by an external force (gravity) rather than sheer willpower. In this metaphor, the writer’s fingers “jerk” to keep pace with the rush of thought, suggesting a state of flow where language arrives faster than conscious planning. The image also implies risk—downhill running can lead to stumbling—hinting that inspired drafting may be messy, impulsive, or imperfect, yet vital and alive. Overall, it celebrates momentum and surrender in creativity: the best writing sometimes happens when you stop overmanaging and let the work carry you.
