Neat ideas. I recall Dan Ariely of 'Predictably Irrational' noting that an effective method of exerting willpower was to mentally associate difficult / cumbersome tasks with positive rewarding ones. i.e. Watching a movie right after taking a medicine w/ many side-effects (so the medicine becomes associated with 'movie time' rather than 'side-effect' time.)
Haha, the point isn't to spend all day watching videos, but to use a funny clip to get yourself into a good mood before tackling something that requires willpower.
