Time is money (aphorism)

Time Is Money is an aphorism that originated in "Advice to a Young Tradesman", an essay by Benjamin Franklin that appeared in George Fisher’s 1748 book, "The American Instructor: or Young Man’s Best Companion", in which Franklin wrote, "Remember that time is money."
The saying is intended to convey the monetary cost of laziness, by pointing out that when one is paid for the amount of time one spends working, minimizing wasted time also minimizes the amount of money that is lost to less frivolous pursuits.
