If you could live life over again, would you do anything different?

I could write a book on the things I would do different (I still haven't ruled out doing that as an option). I think the main thing I would never have done is started smoking. I have been smoke free for over 2-years now, but I swear I still have bad effects from it. I don't know for sure that smoking is related to some of the problems I have now, but I wouldn't be surprised if that were the case. I also would have never started drinking. I would probably have a lot more money and a few less scars if I had just stayed away from those two things. Life has been one hell of a ride so far, but I have also paid a lot of dues. I think my life is getting better with time. I have a house of my own and a good wife. I guess that alone is more than most people can say. I am still struggling a little financially and career-wise (starting a new job at the end of the month, I hope this one works out,) but over-all, things are looking up. I just turned 30, and I think the next couple of years are going to be pretty good...I am actually looking forward to it I think...

I know this sounds stupid, but I would change my hair habit. I have a really bad habit of pulling out my hair. And it makes my mom really mad, so that's one thing I would really change.
