Anime, Manga, Cookies, and Self-Control

Do you ever use anime or manga as a reward?  You tell yourself, "Okay me, let's get going here.  If you can  survive your 20 hour Tuesday and submit some piece of creative writing to a magazine, then the next day, you can watch Y!" 

It's seriously like rewarding kids with cookies (very expensive cookies), only it's yourself you're rewarding.  It's just a way to try to be disciplined.  Unless it's just me . . .

Have you ever held off watching/reading an anime/manga until you were done with some necessary vegetable task?  Which ones?  Do certain kinds work better than others?  (And what ones have you failed at holding off on because you just can't concentrate on anything else until you read/see it?)
