Most people who have narcissistic traits, which is most of us, do not qualify for a diagnosis of NPD. What is the difference between a person who has "narcissistic issues" and one who is pathologically narcissistic?

When referred to in everyday language, people who have narcissistic traits are often said to have "big egos".  This means that they get obvious gratification from being admired and demonstrating that they are special. They may brag about accomplishments and become prickly and defensive when questioned about them.
