Its a historical quote from Ernest Shackleton when he was recruiting the crew for infamous 1914 Imperial Trans-Antarctic Expedition with ads in London newspapers that read:

MEN WANTED: For hazardous journey. Small wages, bitter cold, long months of complete darkness, constant danger, safe return doubtful. Honour and recognition in case of success. Sir Ernest Shackleton.

I very highly recommend the book - http://www.amazon.com/Endurance-Shackletons-Incredible-Alfre...
