I remember the house I bought when I first set foot on Canada. It was a Period 7 house facing Ren (N1). The bedroom in the NW had the stars 1 and 4 and I assigned it to my elder son who was about to graduate from high school. Well, he improved a lot from the days when he was in Hong Kong and was admitted into the University of Toronto. What was more amazing was that he was never short of girl friends. As a result, his academic achievement was quite limited.
Then I assigned the room to my younger son. He was always among the best in high school and university and got a good job after graduation. He also got married with his high school sweet heart.
The same stars when used by different people will generate different results. Some people can use the star for academic achievement while others may use the star to become an artist. The same stars can also be used by some people to become romantic people flirting all the time.
The nature of a star does not change, the outcome depends on the user.
