Particularly for you true dweebs out there, this is a conundrum. Fortunately, most of you were sufficiently distracted, bored, or lazy enough during your second and third years to not take things too seriously. You do need to be serious, but judicious, in practice. A little perspective, s'il vous pla t. Practice and academics have very different purposes.
Law review is even farther off the theoretical end of the scale.
Remember too that discussions of law review come up rarely in practice, except among the insecure. Smart Senior litigators look for the lean and hungry look, which is rarely found in hallowed halls. When assigned a case, grab hold and do a kick-ass job. This should not imply that you need to be rude, or dishonest, or needlessly crafty. This is, after all, how law reviewers learn.
