“Sometimes the noes are just as important as the yeses because they represent cul-de-sacs, allowing you to narrow your field of inquiry until you stumble into the heart of the maze.”

“Stick with the Dips that are likely to pan out, and quit the Cul-de-Sacs to focus your resources”

“The Cul-de-Sac ( French for "dead end" ) ... is a situation where you work and work and work and nothing much changes”

“A committee is a cul-de-sac down which ideas are lured and then quietly strangled.”

“The road simply ended. No cul-de-sac. No sign like the ones they had seen before: "Private Property. No Trespassing." Or "No Motorized Vehicles Beyond This Point." Just road...then trees.”

“So it goes for those of us who live in a cul-de-sac, where babies are brought home from the hospital and watched over, where hearts stop and feet slip, where we wonder if there is a hidden road that leads somewhere.We believe and we doubt. Believing and doubting share the same inevitability, but they are not equal. They cannot lay the same claim on our allegiance. They do not share the same power.If there are places beyond the cul-de-sac, doubt cannot take us there.”
