"Success is Counted Sweetest"

From Tardis Wiki, the free Doctor Who reference
Success is Counted Sweetest

"Success is Counted Sweetest" was a poem by Emily Dickinson. It began with, "Success is counted sweetest by those who ne'er succeed." Kathy Swanson remarked, "She was a bundle of laughs!" after reading this line.

She and Jack Harkness tried it out as a possible passcode to unlock the Torchwood Hub, but it was actually the ISBN to Emily Dickinson: The Complete Poems. (TV: They Keep Killing Suzie)
