For another perspective, check out the book, "Scarcity: Why Having Too Little Means So Much" [1], which claims it's not just about will (executive function), but also about tunnel vision and reduced fluid intelligence, all caused by a situation of scarcity--time scarcity in the case of procrastination. And they claim reduced executive function is situational. It's not a fundamental attribute of the procrastinator.
