William Shakespeare on Prudence

“Think him as a serpent's egg Which, hatch'd, would, as his kind, grow mischievous, And kill him in the shell.”

“Love all, trust a few, Do wrong to none: be able for thine enemy Rather in power than use, and keep thy friend Under thy own life's key: be check'd for silence, But never tax'd for speech.”

“In my school days, when I had lost one shaft, I shot his fellow of the self-same flight The self-same way with more advised watch, To find the other forth, and by adventuring both I oft found both.”
