I’ve been thinking about the marshmallow test off and on for years, ever since I heard about it. I am positive I would have waited for the second marshmallow. In fact, I think there’s a good chance, when the second one arrived, I would have let that one sit as well, thinking I could be the first four-year-old in history to be awarded three marshmallows. Of course, I now realize that, instead of getting a third marshmallow, all the other kids would enjoy their marshmallows, the researchers would turn out the lights and leave, and I’d be left alone in the room until the janitor showed up.
