i do the same thing lol all the time.. i have to make my self keep working with no breaks ..breaks make you want to not do it any more.....just keep working on what your doing..even if you want to stop and take a break. when i do this, i some times get in to what im doing and then i dont want to stop tell im done..but that just works for me, it may not work for you...also try to make it a game..like say,, if i paint or do something ans i dont want to, i say to my self if i paint or do this much by this time i well buy me a candie bar at the gas station or get that new shirt ive been wanting,,but when i do finsh in time i tell my self " ok if i do THIS much more then i well not just get the candie bar i well get a drink to" it works some times on me to know i well get something for doing something i dont want to do lol....
