Some say that it just comes at random especially when least expected. It is also a belief that develops from random incidents that happen repeatedly with the same cause.

    For centuries, symbols or items of luck are found.

In the US, Europe and Africa the "rabbit's foot" is considered a charm to bring good luck so many stores sell key chains of it, this legend was started by the Americans belief the a rabbit's hind foot brings good luck to life.

     Opening umbrellas indoors, walking under ladders, coming across a black cat, does that seem familiar? Those are myths that people believe will bring misfortunes. There are stories behind those sayings that our ancestors created many years ago because of repeated incidents they experience happening from the same cause. Folklores can also be a cause of developing ideas for sources of bad luck because of beliefs of a certain god not being pleased or stories developed by a certain group.

     These days the youth have developed their own sources of luck. For example, if there is a test with exactly the same pen used, there is a good result after, as always it is caused by repeated incidents which cause the user to believe that the item has a supernatural force that brings good luck. Tossing coins is also a belief of luck since people believe that two sides of the coin has a meaning. The front also known as heads is believed to be the positive outcome while the back or tails is known to be the negative side. Wishing wells are also a part of lucky beliefs since most children believe that tossing coins into a fountain brings luck and grants wishes. Haunted houses in pop-culture are said to e places where everything bad occurs since teenagers these days create stories about what went on to be the cause of the houses negative aura. Beliefs of luck also comes from rumors that majority immediately believes like with internet messages that one persons posts and everyone's believes it.

     All this talk about luck gives us the outcomes in life whether good or bad. I choose to focus on the positive outcomes rather than the negative ones and I hope everyone does the same. we can always focus on the positive because as the saying goes positive thoughts gives a higher probability of a positive outcome. A cause of good luck can also be based on a persons aura,which reminds me of what my mother used to tell me that a positive attitude attracts positive forces while negative attracts negative forces. If it comes to tests and exams luck is actually a state of mind since there is a feeling of the effort used on studying paying off and the confidence gained.
