As I've gotten closer to goal, I've really had to shift my thinking. For so long, it was "lose weight lose weight lose weight" that it became daunting to me to think about what life would be like once I reached goal. As I truly started shifting my focus to maintaining my healthy lifestyle, it didn't seem so frightening.
The weight is still coming off, but my real joy is now trying to a new exercise class, or taking an hour-long walk during lunch, resisting temptation when I go grocery shopping or finding a new healthy food or recipe. At the end of the week, I don't always weigh myself anymore, but I do still journal my food and exercise.
My point is, and I do have one, I was concerned about -- "what am I going to focus on once I hit goal and I don't have that gratification every week of losing weight?" The answer is, I focus on the overall lifestyle and I congratulate myself along the way for each accomplishment! Focus on all the great stuff you're doing for your life and health and celebrate everything, not just the pounds dropped.
