In an article I wrote a few years ago called Do It Now, I explained some time management techniques that allowed me to finish college more quickly than usual. What I probably didn’t make clear in the article was that I didn’t overwhelm myself like a workaholic to pull it off. I had a great deal of leisure time every week, including taking at least one full day off each week. I stole time for doing extra homework mainly from the inefficiencies of school itself, not from my personal time. Some classes require concentration for the entire duration, but at least 80% of them don’t. How much cumulative time during a typical one-hour class are you fully engaged in listening, writing, or doing some kind of mental or physical activity? For me it was probably about 10-15 minutes per hour on average. The other 45 minutes would be spent waiting for the professor to show up, waiting for the teacher to finish the opening babble-talk, pointless administrative and announcement talk that could have been eliminated with a handout, hearing further examples and explanations for a concept I had already grasped, hearing students ask questions for which I already knew the answer, and lots of digressions into the professor’s nostalgia for the 60s (or worse, the 70s). So during a one-hour lecture, I would put this wasted time to good use by doing schoolwork for other classes, whereas my other classmates would spend a lot of time looking bored and not be fully engaged most of the time. So one of my greatest discoveries was that I could reclaim this wasted time during classes themselves and put it to good use. Instead of sitting there bored, I kept myself working. And this worked so well that I actually did most of my homework during classes, so I didn’t have to do much extra work outside of class.
