I don't take the specifics very seriously-- I don't try to analyze everyone in terms of MB-- nor the the Enneagram, which I also find somewhat useful. Occasionally, I find someone who seems to have a very strong tendency towards some of the traits described in a system, but most of what I get out of these systems is a clue that people are very varied, that it's normal for people to be different from each other, and some ideas about possible differences.
