You wake up at the crack of dawn on the first day of the month, dedicated to your new goal of physical fitness. You diligently set off on your chosen activity. When it’s over, you’re tired and sore, but you feel great. This feeling only improves throughout the weeks you stick to the program. Your mood is better, you accomplish more, you eat better without even thinking about it, and you know your efforts are warding off potential health problems. Then one day you’re too tired, and you miss your morning run. Then another miss, and soon you’re back to feeling sluggish and planning to exercise someday in the future. We’ve all been there and often wondered what brings about such rapid changes in our well-being.
