“What is the speed of dark?”

“Faith is belief in what you cannot see or prove or touch. Faith is walking face-first and full-speed into the dark.”

“Put me on a train with no windows where nighttime lasts forever and a speed-mad engineer with a mechanical heart high balls a coal-black engine through time tunnels like a bullet leaving a gun where the speed of darkness is faster than the speed of light.”

“An ordinary mirror is silvered at the back but the window of the night train has darkness behind the glass. My face and the faces of other travellers were now mirrored on this darkness in a succession of stillnesses. Consider this, said the darkness: any motion at any speed is a succession of stillnesses; any section through an action will show just such a plane of stillness as this dark window in which your seeking face is mirrored. And in each plane of stillness is the moment of clarity that makes you responsible for what you do.”

“The SEALs place a premium on brute strength, but there's an even bigger premium on speed. That's speed through the water, speed over the ground, and speed of thought. There's no prizes for gleaming a set of well-oiled muscles in Coronado. Bulk just makes you slow, especially in soft sand, and that's what we had to tackle every day of our lives, mile after mile.”

“The speed of your success is limited only by your dedication and what you're willing to sacrifice”
