warning: listening to random people online who claims to be top whatever percent of their class can lead to miserable first year experience. Do study. Do prepare. Do whatever it takes to learn the law. Understand the structure of law school. Most of the advice people give are 'common sense' that you already know, but won't help you at all once you get to law school, this is because law school demands many things from you that you might not have. Understanding this can take a long time, especially for those who are stubborn about their approach. Be humble, but be smart and selective about what you listen to. Don't listen to trashy advice. That's deadly.
I don't know you (OP), so take my advice for what it's worth.
Can't emphasize this enough: it's not about "prepping" or "burning out too soon" or any of that. Those are signs of bad habits, which abound in law school. If you're doing law school right, it's not a chore, it's not (excessively) hard, and it is fun.
I read Law School Confidential before my 1L year, but I don't know how much it prepared me. I can tell you the 1st couple weeks felt like being tossed in the middle of a forest and having to find my way back because you have to figure out how to read the cases, figure out how to study, do a ton of reading, stress about the Socratic method, etc. (plus I was doing a 4 hour per day commute the 1st 6 weeks). However, everyone in my section seemed to be lost at first. After the first 2-3 weeks, you start figuring it out. Then, at some point it all just clicks and you know what to do.
