A useful mental model for reasoning about behavior change is the Transtheoretical model – sometimes also known as the “Stages of Change” model. Furthermore, the separation of “contemplation” and “preparation” acknowledges that it’s OK to separate deciding to decide from the contents of the decision. Note that the process can end at (roughly) any phase: precontemplation could end with you finding something in your current city that appeals to you enough subconsciously to put the unease at bay; contemplation or preparation could result in you realizing that moving is infeasible, for one reason or another.
