Grocery Shopping

When you go to the grocery store to pick up items you need, I have found you need to make a list, and don’t go while you’re hungry. The reason being, if you have a list, you are more likely to get the items on the list only, and if you go while you are hungry, then you will buy most things that appeal to you at the time. For instance, I went to the grocery store tonight to pick up a container of vanilla Ice Cream, I was hungry when I arrived, and had spent over 50 dollars when I left. Will I ever learn?
