This small chunk notion works with food-related bad habit breaking too. Replace it with the good choice, the gift of life energy, when you choose healthy food over unhealthy food.
What will you choose to do for your health today?
Don’t worry, don’t sweat, the small decisions regardless of what you decide. In the big scheme of things it’s only one choice out of millions of little choices you make daily towards a healthy lifestyle or away from it. It’s just one scoop of sand each time. Don’t sweat it, just know that if you choose to eat that cookie you will have a sugar rush, a crash, cravings, and feel starving because there’s nothing healthy there.
