Can someone explain to me how is it that someone with a strong metal element would need to use fire as a booster when I read that it should be earth? Since you are a strong yang Water, you don't want to be too overly strong otherwise, you will not be able to control yourself. Thus, you should increase yourself with your favourable elements as follows. Favourable Elements Most Favourable Element Colour: green/brown Favourable Element Colour: yellow Unfavourable Elements Most Unfavourable Element Colour: white/gold Most Unfavourable Element Colour: blue/black/gray This is a very important concept for you to improve your luck.
