Stop drinking. I start a good job with some responsibility this year, it's time to settle down my lifestyle a bit. Well, a lot. I've got to the point where I don't really like drinking but continue to do it, so I figure now is a good time to just pack it in, at least for a while until I settle in.
I'd love to give up smoking as well but I dunno if that'll happen.
Be better with money. Much better.
