Just as physical fitness affects our ability to succeed at physical activity, so change fitness affects our ability to succeed at the change process. Physical fitness isn’t something you can see directly, but you can see how it affects our lives, and it can be measured. In a similar way, change fitness affects our lives and it too can be measured.
While physical fitness describes real things about our bodies, change fitness describes real things about our thinking. Change fitness is a form of psychological fitness – we are talking about what we think, how we think, how we see the world and our place within it. It affects the what we understand to be true and real about life, how we speak of it, how we interact with others, and how we behave. All this affects how successful (or not) we are at handling change.
