What Is “Mental Waste” and How Can It Be Identified in Daily Life?

Defining Mental Waste

Mental waste refers to any thought process or behavior that does not contribute to quality of life—and may even harm it. This can include repetitive thoughts, repeated checking, or attempts to control things that are beyond our control. Similar to waste in industry, it represents inefficient use of limited resources such as time and energy.

Examples from Everyday Life

People with OCD are very familiar with the feeling of getting “stuck” on a thought or action. For example, repeatedly checking whether a door is locked or endlessly analyzing a “scary” thought. These processes may seem to provide a sense of control, but in reality, they create unnecessary overload and wear down the mental system.

How to Start Identifying and Changing It

The first step is awareness. By beginning to observe thoughts and actions through a lens of efficiency, it becomes possible to identify which processes serve us—and which do not. From there, small changes can be made: reducing repeated checks, shortening unnecessary processes, and choosing more effective responses. Over time, these changes accumulate and lead to meaningful improvement.
