meyers-briggs deja vu

Found this online meyers-briggs type personality test. I took it and it seems my default personality settings have really not changed much since the last time I took a test like this (15+ years). On the one hand, I'm a little surprised. I don't feel much like the person I was 15 years ago. I have a family now, I've actually mellowed, I feel I've grown spiritually, and I hope I've grown wiser and more patient. On the other hand, it is comforting to know my core personality remains intact and I hope I've learned how to grow beyond some of the negative traits that come along with the package that is me.
