Luck is a hard thing to prove. There is no real thing we can call luck, but we can create a real object and transfer luck to it, such as a lucky penny or a lucky charm.

These lucky objects give the feeling of a security blanket. They provide an illusion of control for the person who believes in them.

• Studies reveal that people perform better on tasks when they have a lucky charm with them. During a series of memory tasks, students who were allowed to keep their lucky charms performed better than students who had their charms taken away.
• Attitude plays a big role in luck. Someone who believes they are lucky will try harder at a challenging task. That persistence can have a self-reinforcing effect. The harder the task they take on, the more chance of success, increasing the belief that they are lucky.
