Resolution or Healthy Life?

Exercise. Why does it seem that this is so hard for everyone? Or atleast why is it so hard for me? I love to play, I love to be active, yet day in and day out, my "exercise" consists of walking to the car, or walking through a grocery store, or just doing nothing at all. I share an office at work with the Diabetes educators, who are all dietitians. Today I was looking through a book they had on the health information at fast food places. Did you know there are 810 calories in a Roast beef and swiss Market Fresh sandwich from Arbys? This is more than any single item at Wendy's or Chick-fil-a. So if you think you are being healtheir by going marketfresh, you aren't. I just don't understand why our world has become so fast paced and so heavily influenced by instant gratification. I don't understand why when I get up in the morning, I am not motivated to get outside, or why after a day of being cooped up in a hospital, I am not more excited about walking around and getting fresh air. I know one reason is because I hate to do things alone, and if I veg in front of the TV, I don't have to think about being alone, or if I sit on the computer and write emails, atleast I am attempting to maintain relationships. I really really really want to learn to be disciplined and self motivated to be active. To get outside on a regular basis and just do whatever, a walk, a bike ride, a hike, a game of frisbee. I don't want to do this because of some new year's resolution to lose weight, or lower my dress size, but I want to do it because if my life is too busy now, it's only going to get busier. I want to do this to be healthy, to have more energy, and to build a pattern and routine so in 10-20 years I am still able to do the things I love. I think that sometimes my excuse is that I can still do everything I love. On a whim I can go climb stone mountain, or water ski, or go on a 10 mile bike ride, or even play a game of ultimate. I am not saying that these things don't wear me out, but the fact that I CAN do them makes me happy. I don't enjoy it, but I am physically able to run a mile, but one day without activity becoming a part of my regular life, I won't be able to do these things. If anyone has any suggestions on how to make this part of my routine, I would love to hear them. I don't think gym membership is an option for me right now, cause I know that's an obvious answer.
