I am 40 years old, but still when making a burrito I almost always put too much filling in it. I get too enthused about all of the yummy ingredients that I end of with this overstuff pillow like thing that breaks apart when I eat it. Then just long enough time passes before I have them again that I forget this lesson. I guess it is sort of like making a pizza, it hard to show restraint, but if you do it turns out so good.
