I would obtain a small library of textbooks on academic subjects and read them all, then reread them, then do all the exercises contained therein several times. In my current state, being without a will of iron, I tend toward less efficient and detailed learning methods like online articles and wikipedia for extra education. I would take maybe five years and revolutionize a field of science after studying it continually, with regard for only my health and basic socialization. Eight hours of sleep, three hours of internet, movies and videogames, and thirteen hours studying and improving on widgets would make for an impressive work output, considering that that would be thirteen hours uninterrupted by distractions, procrastination, or sudden desires to scream.
