A "lucky charm" is an object that people believe brings good luck or positive outcomes. These charms can take many forms, such as a four-leaf clover, a horseshoe, or a special piece of jewelry. Many cultures have their own unique lucky charms, often passed down through generations. People often carry or display their lucky charms during important events, like exams or competitions, hoping to enhance their chances of success. While the effectiveness of lucky charms is not scientifically proven, they can provide comfort and confidence to those who believe in their power.
