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.
