For the longest time I would tell people that I didn't expect to live to see thirty. I don't know if I believed it or not, I don't know why I particularly felt that way (no doubt my foray into eschatology informed that decision), but as I've gotten older I've moved away from that mindset.
So today is my 29th birthday. I have a job that I'm interested in turning into a career. I have a wife. There's talk of children. We have a house. So this is sort of a symbolic transition for me into a more future-centric living model. A year from today, I will have been wrong. And I'm pretty much okay with that.
