“Dad always said you’ve got to stay flexible. We never went on a family trip nor have we ever heard of a business trip in which the schedule was not changed at least once after the trip was underway. Later, we all snickered at some writers who viewed Dad as a grand strategist who intuitively developed complex plans and implemented them with precision. Dad thrived on change, and no decision was ever sacred”.
–Jim Walton, son of Sam Walton, founder of Wal-Mart
