Here is a list of six common Cuban traditions and superstitions for good luck, happiness, attraction, and warding off evil:

Good Luck

Put a glass of water in a corner or on top of the refrigerator. It will counter any negative energy and bring you luck.

Meanness

If someone is being mean to you (or you have an annoying boss) and you want it to stop, write the name on a piece of paper. Then, place it in glass of water, and store it in the freezer.

Happiness

When you open a bottle of any kind of alcohol, put a little in the corner of the room behind the door to share your happiness with the saints. Don’t be selfish, lest you make them angry!

Attraction

When you want to attract someone (e.g. a romantic partner) or something (e.g. a job), put sugar in a glass of water and put the the name of your object of attraction on a piece of paper in the water. As a result, you will sweeten whatever you want to attract.

Evil

If someone is being really mean to you put that piece of paper with the name on it in boiling water.

Beyond Your Control

If you have an exam or visa interview or meeting with a lawyer (basically any important paperwork type event that is out of your hands), light a candle and leave it on. Therefore, it will show you the way.
