I read a Japanese Feng Shui guru, Dr. Copa's book every year. According to his book, to strengthen your money luck, you need to clean the west side of your house first, then put some yellow and white stuff (flowers are the best) there. It is not good to have bathrooms or your kitchen on the west side of your house, if you do, you have to make sure you keep those areas very clean.
Unfortunately, my house has a bathroom on the west side. Actually, I need to clean there, so I will now!
