I have to admit one thing hasn't changed for me, and that is my insistence that the scale keep moving down. I'm all for non-scale victories, but that number needs to keep moving down.
That being said, I do spend a lot more time focusing on what I can do that I never imagined being able to do. Running might be the newest, shiniest short term success that will keep getting better, but I keep thinking about my sense of accomplishment and confidence that I can tackle anything. (Although some things might need a ton of practice to succeed at.)
I'm mostly dreaming of the day where I can finally stop focusing on losing weight and just maintaining. But that is still quite a way off. I have lots of goals that I'm working on, like my career change, hoping to the Disney half marathon either in 2009 or 2010, and to just be part of a relay team for a marathon this year. But it's nice to just wait and see what I can accomplish that I've never even thought about. I'd never have guessed I'd be where I am today in my fitness and self confidence levels.
Hopefully I've built enough variety into my life to keep things fresh and interesting, but I also am aware that I need to watch for signs of burnout. I get very caught up in one or two things and overdo them if I'm not careful. (This can also apply to what I'm reading, what I'm cooking, and my hobbies.) Plus, once the snow stops coming back after melting, I can finally get back into some of my favorite warm weather hobbies.
Life is like a roller coaster, with lots of ups and downs, but the curves, spirals, loops and corkscrews are what make life interesting.
