Not to be confused with the Lazy Brains, Procrastinators get all of their work done, they just get it done very late. Usually it's a result of being constantly distracted by things going on, such as their phone, family, friends, the cool looking airplane that's flying by the house, and that darn season finale of that show they've been dying to see for weeks! Any little thing can distract them from their work and it's often very difficult for them to get back on track. On top of that, if a particular homework seems very difficult or easy to do, they may hold off on it until the last minute as a result of dreading the work or just thinking it'll be easy to knock out right before class. It may not be a great final product, but they at least do get their stuff finished.   

Eventually.
