To get into college, get off Facebook

Cal Newport
says that by working smarter, high school students can develop what he
calls an "under-scheduled life" that will leave you with better grades,
more college acceptances and–here's the best part–all kinds of free
time.  In fact, he says that students who do this right can finish all
their work by dinnertime almost every day and have the rest of the
evening to do pretty much anything.  Here's one of his most important
tips:

Rule #6: Do not, under any circumstances, do any work anywhere near an internet connection.

Do
not do any work while online.  If you're writing a paper, or working on
math problems, or taking notes on your history textbook, with an
instant messenger window open, there's absolutely no way that you can
realize the ideal student workweek.  The work done in this state is
poor, it is draining, and it takes forever.  If you work while online,
you will end up staying up late, you will end up doing shoddy work, and
you will fail to achieve an underscheduled lifestyle–and therefore lose
all the benefits that it generates…When it comes to productivity,
there's no avoiding this truth: Facebook is the tool of the devil.  If
you want to significantly reduce the time you spend working, then you
absolutely have to keep the internet far, far away until you're
completely done for the day.

*Note: Cal also makes it clear that he's not against Facebook or
anything else you might like to do–he's just arguing that you need to
separate your work time from your free time–and that letting them overlap just
ruins both.
