Impulse refers to a sudden, strong urge to act without thinking about the consequences. It often leads to quick decisions or actions that may not be well thought out. For example, someone might buy an expensive item on a whim, driven by an impulse rather than careful consideration. In psychology, impulse control is the ability to resist these urges and make more deliberate choices. People with strong impulse control can think through their options and avoid acting on fleeting desires. This skill is important for making responsible decisions in various aspects of life, including finances and relationships.
