Edges can be big or small. For example, people can have edges about taking on new responsibilities, speaking out, or asking for help. We feel that we need to speak out, but we are afraid of how it will change our lives. We feel that we need to change jobs, but we are comfortable where we are. We need help in doing something, but we are too embarrassed to ask for help.
People often become confused and forgetful at edges.
When resistance asserts itself we can temporarily forget why we are doing it. We may have trouble holding in mind two conflicting points of view at the same time. Psychologists observe that people approach an edge and then back away, only to try again later. The urge for the change drives them forward, and resistance to the change drives them back. It is not always wise to urge someone to cross an edge.
