Full metal-head in his 30s here, gotta admit I am a much different person and much happier now than when I was 22, sometimes I would like to go back in time and punch my younger self. The body is failing already, but the spirit is getting stronger.

I'm also happier at this stage of my life (turning 30 this year) than in the past, but I have to wonder how much is my personality and how much is circumstance. I'm married, we have our own place to live, I have a relatively successful career, I have friends, and I can pursue my hobbies more or less freely. Those things weren't all true for me at 22.
