ENFJ's tend to be more reserved about exposing themselves than other extraverted types. Although they may have strongly-felt beliefs, they're likely to refrain from expressing them if doing so would interfere with bringing out the best in others. Because their strongest interest lies in being a catalyst of change in other people, they're likely to interact with others on their own level, in a chameleon-like manner, rather than as individuals.

--Portrait of an ENFJ

Last night I had a personality breakthrough.  For a while now, I've thought that I was an ENTJ, but after perusing some of the descriptions for extroverted types, I realized that it's not quite right.  The F and the J might be close, but I'm definitely an ENFJ--and so many things make so much more sense now that I know that!
