People with controlling personalities feel a compulsive need to be in charge of their environment and dictate other people's behavior. They are unable to admit mistakes, assume authority without being asked, always insist on being right, are hostile to criticism and micromanage friends, family and co-workers.
Controlling personalities are motivated either by a pathological need for dominance or by an in-built anxiety over losing control of their lives. The first often bullies other people into conforming to their desires while the latter tends to over plan or over schedule their lives in order to avoid uncertainty. They spend an extraordinary amount of time planning their activities and organizing their environment and become extremely upset when events to do unfold according to plan.
