Shooting stars tend to be associated with a moment in time that left a lasting impression, whether a short romance, special event, a person, job, anything that may have changed the person's life.
Before modern navigation sailors navigated by using the stars- usually the North Star. They often got tattoos of nautical stars in a superstitious sense, hoping that the star would help them get home safely.
The nautical star is often a symbol of protection and guidance. Some see nautical stars as a means to create your own path.
