"There is a vast world of work out there in this country, where at least 111 million people are employed in this country alone--many of whom are bored out of their minds. All day long. Not for nothing is their motto TGIF -- 'Thank God It's Friday.' They live for the weekends, when they can go do what they really want to do."

-Richard Nelson Bolles, What Color is Your Parachute?, 1970

(Does this mean he coined the phrase "TGIF"?)
