Metal Turtle in the North
Place a metal model of a turtle or terrapin in a small bowl of water and keep it in the north zone of your home.
The turtle is a good enhancer of longevity and also, in the north, it is an enhancer for career opportunities.
You should just keep the model of metal turtle alone, without the water bowl, if you happen to have a bedroom in the north zone of your house, since keeping water in a bedroom is not advisable.
Keeping an actual/real turtle/terrapin, in a small vessel of water, in this area is an even better enhancer, but the metal turtle works well too.
