Meal portions are too large. It takes a certain discipline to have a meal, like this 5-star chicken alfredo, decide to only eat half, and commit to that. Especially when the second half won’t be as good: the chicken too cold, the spaghetti too burned, the atmosphere too dull. Yet, practicing the discipline to say, “no, I’m good” to overindulgence is probably the third greatest feeling in life. This delaying gratification becomes easier with practice.
