Have you heard of Feng Shui? That is the Chinese art of applying numbers in everything that is related to your habitat. My sister-in-law is a Feng Shui practitioner and as I had seen her do Feng Shui, she would take note of the surroundings with a compass in her hand and measuring things with a tape measure (the bigger one used by carpenters). She said that our life is greatly affected by the position of things like the location of the house inside the lot, the location of trees and plants and so many other items that would probably needed rearranging. After a day, the Feng Shui master would come back with the analysis, normally about 2 to 5 pages outlining the changes that the house owner should make. It can be the color of the wall or an entire room, the kind of door that would give you more luck... yes, it's all about getting good luck. It looks silly to believe in such things but I wonder why rich people have their Feng Shui masters to chart the luck in their life especially for the business.
