then just give it a try yourself, for the sake of it. get a very tiny goal, like "today i am going to study/work for at least x hours, just to see how it is. tomorrow i'll go back to doing nothing or whatever it is that i like best". this way you don't stress yourself with unbearable longterm goals, you just experiment and you know that if you want the effort to be over in 24 hours it will be. if at the end of the day you find that you feel rewarded by what you have achieved you try again the following day, with no panic and no expectations. if it works for several days then weeks you'll possibly find yourself with force of will, because you will have positive feelings to associate with doing something that is against a concept of instant gratification, and this is one of the two forces (the other being some cathegory of ethics, but that's far harder, and anyway it is not something that can be imposed on other people or even suggested) that i think are behind willpower.
whatever.
