Was reading another blog post where the author mentioned his Myers-Briggs personality type. When I took the test a couple years ago at work it said I'm an INTJ. From the current wikipedia page:

INTJs are strong individualists who seek new angles or novel ways of looking at things. They enjoy coming to new understandings.

While I take things like the Myers-Briggs test with a grain of salt, that seems about right to me. If you are interested, take a look at the rest of the INTJ page and if you know me, judge for yourself.
