I have been so intrigued by this lately. I'm a teacher and I discovered this through a TED Talk I believe. The marshmallow experiment puts a young child in a room. The child is given a marshmallow and told that if he waits and does not eat the one he has now he will be given another one later. The child is watched or video taped and you can see the struggle as he or she wants to eat the marshmallow.
I find I struggle with this in various aspects of life. I know if I wait on somethings I will get better results, but I want what I want now. This could be applied to financial decisions, diet, and even dating.
I always tell myself when I know I'm in one of these situations, "Don't fail the marshmallow test." I still do sometimes, because even at 40 it is still difficult.
How do you pass the marshmallow test?
