They say your perception of time moves faster the older you get, and I have a theory it's because people stop learning and evolving as they age. That's one reason I love the Seattle area; sailing, camping, good outdoor rock climbing, yoga, rainy-day reading, and generally good opportunities to be with friends are all things that make me excited to be where I'm at.
Also, I'm reading a book about introversion (I know, right?), and just learned a new word to describe myself - an ambivert! Just took the Myers-Briggs test, and came out ENTJ, but only an 11% preference on everything but N, which I doubt is statistically valid given 72/4 questions for each letter... I guess this last sentence is probably more telling than my score :)
