Clover
To find four leaf clover is good luck. But a five leaf clover brings bad luck.
black cat
In Britain, a black cat is lucky. You can find many greeting cards and birthday cards with black cats on them.
Mirror
It is very bad luck to break a mirror because the mirror shows our soul. So when we break a mirror, we break our soul.
Rabbit
It is good luck to say "white rabbit" 3 times on the first day of each month. It is also good luck to carry a rabbit's food with you.
Leaves
To catch a falling leaf in the fall means good luck. Every leaf you catch means a lucky month next year.
Salt
some people carry small bags of salt with them so that everything goes well in their day. To spill salt is bad luck though.
Horseshoe
A horseshoe over the door brings good luck. But be careful. You need to hang the horseshoe the right way up. If it's upside down, all the good runs out.
