A few years ago, a good friend of mine, Professor Dan Weddle (UMKC Law School) wrote this for the benefit of our academic support colleagues:

One of the best pieces of advice I received before attending law school came from a friend who had just completed his J.D. at the same school a year or two earlier.  He said, "Don't look horizontally."  By that, he meant that I should not worry about what other first-year students were doing because they may be doing all the wrong things.  Hearing from a fellow student that he "studies every night until 2:00 a.m." can be terribly misleading; for all anyone knows, that student does not begin studying until 10:00 or 11:00 at night and is in fact experiencing significant diminishing returns almost from the outset of each study session.   He may also be blowing smoke.

Professor Weddle is absolutely right. There are a couple of reasons the horizontal view has no value. The first is the one Professor Weddle raised about smoke.  Count on lots of smoke.  Not to disparage the profession, but remember, these students are aspiring to become lawyers.  The example in the preceding paragraph does not include a false statement ... but it sure wouldn't sound so convincing if all the facts were spelled out.

A second reason, perhaps more important, is that each of us has our own way of learning.  One student may learn optimally after dark, while another can only study efficiently after sunrise. I'm a tactile/kinesthetic learner, so sitting on my butt in a library for 8 hours is not as productive as standing at a blackboard in an unused classroom, pacing around as I diagram a flow chart on the board in several colors of chalk. 

Don't get me wrong, there are MANY study basics that are essential to learning the law so that you can achieve your goals ... but once you master those (what I call the Law CATS ... see other parts of the web page for more on that), or even AS you are mastering those, don't worry about what others are doing.  You're in law school to do YOUR personal best.
