Time’s True Value

“Time is money.” It’s an age-old business adage, popularized by Ben Franklin’s Advice To A
Young Tradesman. Franklin argued “He that loses five shillings worth of time loses five shillings, and might as prudently throw five shillings into the sea.” Since then, the phrase has been used to exhort business people of all kinds to work more hours.
