Ruminations on change surround us: “the only constant is change” (Heraclitus); “change is the law of life” (John F. Kennedy); “if you don’t like something, change it” (Maya Angelou); “a change is gonna come” (Sam Cooke). And yet, with all of our conversations about the inevitability of change, we are often ill-equipped to manage it, let alone lead ourselves and others through it.
