When I read, I can unnderstand every well-written character to the point where it seems like I am just like them. In many situations, I can see me doing the exact same thing. However, one character I truly identify with, problems and skills and all, is Jon Snow from A Song of Ice and fire. Seriously, that guy is just like me: Same reactions, behaviour, motivations etc. He even has the problem of being seen as arrogant when he merely wants to help! I think he must be INFj.
