Why don't continents move? Why don't people change?

People don't change because they can't, don't want to, don't know how, or don't know what to change. The transtheoretical model provides an integrative model for understanding reasons for not changing, as well as readiness to change. Stages and levels of change guide therapists in their work in helping clients change. Clients in the precontemplative stage typically cannot change without special help. Those in the contemplation stage are not sure they want to change. Those in the preparation stage are afraid they do not know how to successfully change. The levels of change help guide therapists and clients on what to change.
