Difficult traits? Hmm...I'm stubborn as an ox (must be cause I'm a Taurus), I always think I'm right, I'm avoidant, don't compromise too well with people (actually not good where communication is involved with other people at all), oh the list goes on and on. I guess I'm a lot like ozzie! I don't believe there is a thing as "constructive" criticism. To me it's just a nice way of saying that you're shitting on someone.
