Chris and Rowan discuss the three different types of change and how we can bring about meaningful, long-lasting change in our lives. The three types of change are incremental change, where we might eliminate or introduce a behaviour bit by bit, pendulum change, where we may act differently for a period of time and later revert back to our original way of doing things, such as undertaking a fad diet, or paradigm change, which represents a more meaningful change in our underlying beliefs and cognition.
