A smooth sea never made a skilled mariner. - English Proverb
Sail Forth- Steer for the deep waters only. Reckless O soul, exploring. I with thee and thou with me. For we are bound where mariner has not yet dared go. And we will risk the ship, ourselves, and all. - Walt Whitman
Like one who, on a lonely road, Doth walk in fear and dread, And, having once turned round, walks on, And turns no more his head; Because he knows a frightful fiend Doth close behind him tread. - Coleridge's "Ancient Mariner. - Mary Shelley
