I don't have problems with not doing anything since I'm flooded with classes and more summer classes and college applications and more education things. Do something... productive. Draw? Study drawing? Study writing? Read anything that interests you? I once tried to look through the origins of the stuff I like, or maybe look at the other anime that this certain studio created, and things. Change your surroundings, for once. Look at what your parents are doing. Do house chores -- which is a pain but then it kills time. Oh, and arrange your stuff! It usually takes a long time because you keep on finding cool things. Once took me five hours just to fix my desk.
Oh, and if you're interested in drawing, and you live in Quezon, why don't you try Fernando B. Sena's art classes? I'm entering as well. Not manga classes, but it is a good headstart. We can meet each other and stuff
