Motivation got you started, but you will need the discipline to stay on the path to health.
Discipline is just choosing between what you want now and what you want more.
You need to maintain your discipline. You are stronger than this, and your goal is too important to give into temptation and buy this bag of taffy. Delay the urge and do anything to avoid buying this junk. Your health is too important for you to give up and succumb to this temptation. Be strong and move on the path to better health. Remember that you have got this under control as you take one more step to meeting your goal.
