Harvard Business School professor Rosabeth Moss Kanter coined Kanter's Law: "Everything looks like a failure in the middle" In this article she says, "Everyone loves inspiring beginnings and happy endings; it is just the middles that involve hard work."
"All new initiatives - big new government directions, business turnarounds, new venture start-ups, new products, or internal process changes - can run into trouble before reaching fruition. Troubles increase with the number of ways the initiative differs from current approaches. The more innovation, the more problems. Problems tempt people to give up, forget it, and chase the next enticing rainbow."
