We don't just project our subconscious feelings onto other people; sometimes we even project onto inanimate objects. If you find yourself getting irritated by things like: elevators, the street lights, your pants, ad infinitum, perhaps that's a good indicator it's time for self-reflection. Perhaps you're angry or upset with something much deeper than the object or person.
An ego is important for personal resilience, but the ego can quickly take over and get in the way of interpersonal relationships. There must be a balance of ego, for personal protection, and empathy, for relationships.
