My hidden ability is Technician, because I work pretty well when the situation puts me into a disadvantage. I like to analyze the field, the terms, and try to find ways to use the things that would hinder me to my advantage. I guess I am complacent in situations where I have the upper hand, and tend to make mistakes from overconfidence, whereas if I'm in a tight spot, I apply the pressure by working harder, thinking faster and trying to turn the tables to my favor. (not cocky)
