Change can be difficult (in the sense that we are dealing with people, who present a LOT of variables) and understated (in the sense that many will underestimate its importance due to a lack of understanding or a willing resistance to thinking it’s important). Change is, however, essential, as pretty much the only constant in life is flux- it’s important to adhere to core principles that may have a bit more verisimilitude, but the issue of how to apply those principles to constantly changing employees, management, customers, products, markets, and stimuli is a constant conversation.
