There are obsession quotes that can help you understand what this word means and why this mindset can be harmful. If you have an obsession then you find yourself preoccupied with thoughts and desires which may be difficult or even impossible to resist for some people. If someone develops an obsession with you then they may harass you constantly, trying to get your attention or achieve the end goals that they have in mind. Sometimes healthy love can turn into obsession when one person is ready to move on but the other person can not let go. Having an obsession with perfection can be a positive or negative, depending on how it is channeled. An irrational obsession may be caused by a mental disorder but this is not always true.
