The late Zig Ziglar, late in his life realized that the "goodness" of life had settled around his midsection and he realized that he needed to do something about it. This was an interesting development because one of Zig's mantras was "checkup from the neck up."
He posted a picture of a man from a men's health magazine on his bathroom wall near his mirror. He was a muscular, slender man, and I would add, fellas, be sure you explain to your spouse what you're doing; otherwise it can get really awkward really fast! But Zig said to himself every morning, "I want to look like that! That's my goal!" And so, every day, no matter where he was, he ran. And regardless of the weather he would run and run until he reached his goal.
You and I have set goals but boy is it easy to let things like weather or a little comment throw us off track. We won't run in the rain and we sure can't run in the cold. Or we say, if our goal is like Zig's, "Any way, I'm running, this cheeseburger won't hurt me!" And we all know the rest.
Set your goals and stick to them in faith, doing what it takes to reach them. Ask God for help and give God the glory every step of that way.
You can do it!
