They're different things. Marshmellow isn't about deferring satisfaction, but about using metacognitive skills to reach an outcome you _know_ beforehand is favorable (i.e. two marshmellows instead of one). If you just find a marshmellow on a plate somewhere, by all means, the best strategy is to eat it.
