“I was surprised, as always, by how easy the act of leaving was, and how good it felt. The world was suddenly rich with possibility.”
Jack Kerouac, On the Road.
It is easily done.
Sitting alone on coarse airport carpet, plane delayed but it doesn't matter because in your mind you have already gone, in this moment of departure all that lies ahead is the unknown.
The unknown is all that ever lies ahead, the act of leaving makes us notice it.
