I read an interesting article on Time entitled Why Exercise Won’t Make You Thin. The problem occurs when you “reward” yourself after a workout. All of a sudden, the calories that you had worked so hard to burn are quickly replenished by a treat or a sports drink.
The same rule applies when shopping at Costco. If you reward yourself for shopping at Costco, all of your hard-earned savings can quickly vanish. While you can save money by shopping at Costco, the total amount saved may only be several hundred dollars a year. And, if you pay $3.00 for a tasty cup of coffee or chai tea latte at the local coffee house a couple times a week, your savings at Costco have just vanished.
