Obsession is a persistent and intense preoccupation with a particular idea, person, or activity. It often leads to repetitive thoughts and behaviors that can interfere with daily life. People may become fixated on their obsession, making it difficult to focus on other important aspects of their lives. In psychology, obsession is often associated with conditions like Obsessive-Compulsive Disorder (OCD). Individuals with OCD may experience intrusive thoughts that compel them to perform certain rituals or actions. While some level of focus can be beneficial, excessive obsession can lead to distress and hinder personal relationships and overall well-being.
