<p>Free time is created by not procrastinating; procrastinating removes your free time buffers. More than anything else, this will likely determine your free time in college.</p>
<p>There are exceptions: WindowShopping, for example, isn't emotionally satisfied with his preparation in coursework unless he's working all the time, and cracks his ass to do everything he can possibly think of to prepare. He's assiduous, and yet has no free time. </p>
<p>On the other end of the spectrum, I was an applied math major and I basically did no real work most of the week, and maybe once a week had a total fire-drill atmosphere of getting problem sets done in a whirlwind pace, i'd take maybe 4-6 hours and do a bunch of stuff and then go back to playing mario kart, developing a website or three, running the housing lottery, singing in my a cappella group, and playing ultimate frisbee. My work schedule was optimized for my desire to have maximum variety in my day, and to have the ability to push classwork around to wherever it fit in my schedule. Freshman year was actually the year I probably worked the 'hardest', but thereafter I just worked a lot 'smarter' - I knew exactly what it took to get an A in any given class, so I allocated time accordingly and didn't have to waste a second more than was necessary.</p>
<p>Of course, I also had to do things like learn half a semester of partial differential equations in the space of 36 hours, complete 7 backlogged problem sets, and walk into a midterm despite not having been to the class once yet. So there's ups and downs :)</p>
<p>Max, I have some news for you, too - if you're not prepared to work hard, the world will pass you by. You've worked hard in high school, to gain acceptance to a university who wants your credentials as a hard and efficient worker, so you can end up working hard for some company down the line (and get paid accordingly). If it is just a 'timeout' that you want, take a year off, by all means. My year off was probably the best thing that ever happened to me. But if your temperament just isn't suited towards jumping through those hoops, period, then columbia may not actually be the school for you. Other schools, not nearly as competitive, may give you less work and you may find it easier to coast to getting straight As. Don't force yourself into a lifestyle you don't want.</p>
