It is really boring to do the same block over and over.... I try to have another more fun project going at the same time, like a sampler or pieced borders or something. Then, in the morning, I won't let myself work on that fun project until I've made one more block. Pretty soon you'll have them all done and have a good start on the other project as well.... oh, and I really like the chocolate reward suggestion too!! Good luck with it....
