Past Life?

I just got done reading some random, old posts from my 5 years as a blogger. It is amazing to see what I have written and how far I have come. As I read, I could see myself in the writing, but not the same self...a much different self from another time. It's very strange, and I almost feel sad. I'm not sure why it's sad and I've actually teared up just writing that. Maybe I miss what I deem to think a simpler time? Maybe I miss writing about being home? Maybe back then I had a direction and now I don't? Then again, maybe it's just nostalgia. I can tell that I have changed from my past writings, though I can't pinpoint exact examples. Inside, I don't feel like I've changed all that much, but I've been told that I have. It's hard to stand outside oneself and see an evolution, but I think through my writings, rants, raves, and nothingness, I can see a small one...and it makes me feel sad and good at the same time.
