It does help to read that site or to get a good enneagram book (the one by Riso and Hudson is good)-- the best thing is get your "subject" to take the quiz.
The thing that we don't talk about much here is the "wings," i.e., the numbers on either side of you influence you a lot. So you have a 4 with a strong 3 wing or a 4 with a strong 5 wing. The way we talk about it here is kind of superficial.
Having said that, it's entirely possible that you're a 2, karen. Two's tend to get into the "helping" professions... you might be a 2 with a strong 3 wing or a 3 with a strong 2 wing.
As for your H being a 4, the 4 is variously labeled the Artist, the Romantic, or the Individualist. The core issue of the 4 is that they feel they are cut off from the source of life. They feel broken, isolated, different, alone.
This is not like horoscopes where there are good pairings and bad pairings. Each type can pair with each other type and it can be good or bad depending on how developed each person is. I think one of the sites we've looked at described what different pairings are like. I also have a book on that, but it's at my house and I'm at my bf's house right now. I'll post some stuff from it the next time I'm out there.
To address the comment Chuck made on the other thread, these types, whether it be the enneagram or the Myers-Briggs are NOT all that you ARE. So trying to grow beyond these lables is not a violation of "to thine own self be true." No one person can be shoved into a box with a label slapped on it. These typologies represent limited ways that you learned to cope with what life threw at you in your earliest life. These are patterns of learned behaviors. That's why Jung suggests that if all of your life you've relied on your powers of rational/logical analysis, then in your later life, try to develop your feeling abilities, your intuition. It makes you a well-rounded person.
All of these systems are tools. They aren't set in concrete. They help us to understand our own quirks and those of the people we live and work with.
