What's normal varies from time to time and from place to place. There are fads in psychology as well as everywhere else, and only time will tell what's just a passing fad and what's actual progress. What I mean by normal is this: capable of loving, working, and adapting constructively to changing conditions and different people.
"Distinctions between Self-Esteem and Narcissism: Implications for Practice" by Lilian G. Katz. This is specifically about primary education but is of general interest. Interesting and well-written (no jargon). Bibliography.
The New Personality Self-Portrait: Why You Think, Work, Love, and Act the Way You Do by John M. Oldham, M.D., and Lois B. Morris [Bantam, 1995] describes fourteen different normal personality "styles" and their companion personality disorders. Descriptions are based on the diagnostic criteria of DSM-III-R and DSM-IV. The book contains a questionnaire for determining your own personality style, and it also has advice about making the most of your style, managing your weaknesses, getting along with people with different personality styles, and also how to cope with people with personality disorders.
You can find brief descriptions of the personality styles, along with questionnaires, here. Here's another quiz, only 20 questions on this one, most of them similar to the Oldham questionnaire: Online Screening for Personality Disorders.
