I feel the same way. When I've done a particularly difficult jigsaw puzzle or made a new dress with a cool original design I do feel proud and accomplished. I also feel very satisfied after finally doing some cleaning task because everything looks clean and nice. But with assignments or exams from school or whatever I don't. The only time I get a true feeling of accomplishment from anything school related is if I've made a really fucking slapping lesson and the kids thought it was fun and weren't out for blood that day, lol.
