Can drawing shows the personality of a person?

I am really amazed of what happened in my Philippine Literature subject last week. Our professor asked us to draw something about a certain topic. Then the following day she let us explain our drawing. I am amazed that she tell something about my personality. 99% of what she said is true about me. I don't know how does she do it. All i know is she just stared at my drawing and then she just said the things that i thought no one could know.

Here is my drawing..

That is not a drawing of a grade school student.. that is my drawing.. a 3rd year Civil Engineering student take note CIVIL ENGINEERING..haha I know I must be good at drawing because of my course but i don't know i rally hate drawing..

Wanna know what did my professor said about my personality based on my drawing?

I am hard headed..if i want something then i must get it even though it is impossible..all the things that i want i must get it.. i also have lots of insecurities that only me knows. I don't know how she knows about it..

Can you tell me how does she do that?I wanna learn it :)
