A good example of the non-linear-ness of the process of change is Dr. James Prochaska's, Stages of Change Theory. He describes 5 stages of "change readiness" - each of which is responsive to certain processes or approaches. People who successfully change a behavior, will not usually progress through the stages in a straight line, but more in a spiral, relapsing some and then moving forward again.
