Relation between Faces and Characteristics

             My face looks like a round face but that's because I got a lot of weight. Originally, I have a pointed chin. Although I do not have a narrow forehead, I chose the diamond type. I hope the diamond face is the closest shape to my face. The article describes that people with diamond faces are warm but they have a strong will. It’s not describing my personality accurately. Usually I am warm, but sometimes I am changed to a cold-hearted person. Moreover, I have a very weak will. I do not do something for a long time. I can be sick of things easily. However, I should do something that I want to do. 
Another example, one of my friends has a round face. The book says she is very intelligent and she prefers to work with her brain instead of her body. Also, it says she is confident and usually lives a long life. In fact, she is very smart and she wants to get a job that needs high intelligence. Until here, it seems correct. However, she is shy rather than confident.  I can't conform she has a long life or not because she is alive.

I think there are no relations between type of face's shape and personality. Basically one's personality is very complex so it's hard to predicate. Sometimes it's changed to the opposite and sometimes one person has both different sides of characteristics. Also, there are more shapes of faces than eight types.
