Congratulations on your decision to get up, and walk to the store. If you are very sedentary...a 1 mile walk IS something. You should be proud that you did it.
I have a strip mall .5 miles from my house as well (grocery store, Hallmark, Blockbuster) and when the weather is nice, I also walk there to pick something up.
I challenge you to do this walk a few times a week. Over time, as your body gets used to it and you have some weight loss-it WILL become easier. After losing 10 pounds for instance, that is 10 less that you have to drag along with you on that 1 mile walk. It may not seem like much, but carry a 10 pound sack of flour around for a mile...and you will see that it is.
Every step that you take, and every pound that you lose-will make it that much easier to keep on going.
