Self-control
Have you ever noticed that obese people are usually poor too.
There are two arithmetic equations. One for obtaining wealth, and the other for staying reasonably slender. These two equations are just the opposite of each other.
The first for obtaining wealth is spend less than you take in.
The second is Take in less than the calories or fat you use on a daily basis. Some diets even say you can cheat one day a week, either by not exercising or having a yummy dessert.
