Often the notion of change is misunderstood by new writers to mean change that is abrupt and absolute, from Scrooge to do-gooder—but this rarely happens in life or in convincing fiction. Rather, change can be as subtle as a step in a new direction, a slight shift in belief, or a willingness to question a rigid view or recognize previously unseen value in a person or situation. Something is visible that was not visible before.
