I've been thinking about this a lot lately.
When I first started thinking about losing weight it seemed so insurmountable. I was at my heaviest 285 pounds. I knew that I needed to lose over 100 pounds. It's such a huge number! For a long time I let that huge number sway me from even starting. I kept thinking there was no way I could lose over 100 pounds, so why try? Why start?
But then I started reading weight loss stories on the internet. I remember reading one on Two Peas NSBR. I can't remember the specific story or the details or who it was. What I do remember is that it took her over a year to lose the weight that she had. That's when I wondered where I'd be at that time if I started a year before? Would I have lost 100 pounds? 50 pounds? Could I really do this?
I ended up reading a lot on the internet about weight loss. One of the things that jumped out was to set small goals. Lose 5 pounds in a month. Exercise 20 out of 30 days in a month. Track food intake for 30 days. Small goals. I realized that if I set enough small goals, they would add up over time. I also realized that if I didn't reach them I could keep going. Even if I didn't reach my goal for that time frame, I had made progress and done something good for me, why would I stop?
So here I am, 90+ pounds down in 2 years and I can look back at my journey so far. I can see that I have made progress. I can look back and see that I'm almost to the top of the mountain. I can see that the journey that seemed insurmountable, really isn't.
My point is, don't let the big goal deter you from setting out on the journey. Don't think about the big goal, think about small, realistic, short term goals. Reward yourself sometimes when you reach them. They will all add up. Maybe not to what you had envisioned, but to something good.
Start now. In a year you will look back as I am doing now and realize that it is worth it. Do it.
