Do you identify most with your physical body, sense organs emotions or intellect?

Kathopanishad says that our entire problem comes because we identify ourselves as somebody else than who we truly are. When we identify ourselves more closely with our body, we end up taking good care of the body which is not going to be with us beyond a 100 years; with our emotional mind then we are swayed to ups & downs of happiness/ sadness; with our intellect, then we are bothered about praise, criticism we get....but what if we realize we are not our body, senses, mind, intellect?
