I've taken the Myers-Briggs test several times now. I take it every few months to see how consistent the results are. Or maybe to see how consistent I am. :) Either way, the results have always come back the same:

I am type ISFJ.

You can decide for yourself how accurate this is:
ISFJs are interested in maintaining order and harmony in every aspect of their lives. They are steadfast and meticulous in handling their responsibilities. Although quiet, they are people-oriented and very observant. Not only do they remember details about others, but they observe and respect others’ feelings. Friends and family are likely to describe them as thoughtful and trustworthy.
