Everybody thinks. Planning, problem solving, and decision making are all helped by thinking. However, thinking becomes overthinking when it becomes unmanageable. Problem solving is not the goal of overthinking. It involves repeatedly repeating the same ideas without coming up with a solution. The mind seems to be working constantly, but nothing seems to be resolved. This behavior gradually starts to rob people of their focus, mental balance, sleep, and peace.
A lot of individuals are overthinking without even realizing it. They think they are simply exercising caution or responsibility. In actuality, overthinking traps the mind in worry and causes needless tension. The first step to overcoming overthinking is realizing how it operates.
