I would say criticism affects me most, but not negatively.
I don't pay too much attention to compliments, aside from general appreciation. But if I'm receiving a compliment that's great, I'm glad the person approved of me or what I've done or said; however, I pay more attention to criticism and I always will. Criticism challenges your world, and maybe your approach is wrong. Whenever I experience criticism, whether or not its constructive, I spend a great deal of time on it. Honestly asking myself if the other person could be right.
I feel that being a Witness shuts you off to criticism. You are taught to believe that how you think, believe, and reason is right and cannot be wrong because you know the truth. That attitude affects more than just your personality in terms of religion, it makes a person have trouble recognizing when they are wrong or out of their depth.
For this reason, I have far greater appreciation for criticism, and work very hard at giving any i receive a thorough consideration.
