In his book ‘Sapiens’, historian Yuval Noah Harari presents a thought-provoking exploration of our species and its evolution through a combination of biological and cultural perspectives.  One of the observations he makes along the way resonates strongly with a key Slingshot premise.

At the heart of the Slingshot Framework is the notion that there is no such a thing as a fully or permanently satisfied customer.  That customers always want what they don’t have.  Here is how Mr. Harari describes this same human trait in his book (page 98):

“One of history’s few iron laws is that luxuries tend to become necessities and to spawn new obligations. Once people get used to a certain luxury, they take it for granted. Then they begin to count on it. Finally they reach a point where they can’t live without it.”
