I wouldn't use the word narcissism to describe this. I'm worried about suggesting too many things, so maybe just consider these two:
1. Your traits and actions, both good and bad, what are they? Can you describe them, in other words, can you describe yourself through them? Try to do it, and do not use the word "am." Try to write down as many as you can.
(In other words, never "I am a fisherman", only "I fish.")
2. Spend time trying to consciously improve other peoples lives. Work through the barriers you have to doing this and your life will improve, too.
Practice these. If it's not immediately obvious why both of these are necessary, give it time.
