Don’t think you can last a week with that object from your wish list on your mind? Work up to it with the 10/10 rule from writer Kristin Wong. When you want to buy something, wait for ten minutes. Then, if you’re still thinking about the item and it costs less than $10, go ahead and get it. But if you’re still not sure after ten minutes and it costs more than $10, put it back. This rule gives your brain time to cool down from the initial excitement of potentially buying something, but you won’t agonize about it for too long. It helps curb impulse buys especially well when you have limited time to shop.
