The quote in its entirety is:
"In an honest Service, says he, there is thin Commons, low Wages and hard Labour; in this, Plenty and Satiety, Pleasure and Ease, Liberty and Power; and who would not ballance Creditor on this Side, when all the Hazard that is run for it, at worst, is only a sower Look or two at Choaking. No, a merry Life and a short one, shall be my Motto."

A General and True History of the Lives and Actions of the most Famous Highwaymen, Murderers, Street-Robbers, &c To which is added, A Genuine Account of the Voyages and Plunders of the most Noted Pirates
by Capt. Charles Johnson
