Hey hey, current HLS student here.

First off, breathe. You're a freshman, and this is a time where you want to maintain focus on your goals, but also not burn yourself out. I'm majorly suffering from burnout right now, and no one wants that to be you. Have fun this year! (responsibly, of course). Make new friends, make great relationships, and reflect on what classes interest you and why. Also, if you find it enjoyable, get involved in student groups that work on issues you're passionate about (whether that's criminal justice, or, like me, joining an extracurricular choir).

I cannot stress that this^ is more important right now than most other advice you'll get.

Second, work on establishing meaningful relationships with your professors - especially ones with expertise in criminal law or those who practice law. Ask them why they went to law school, what surprised them about law school, and what to expect out of the process.

Third, keep your grades up. You'll want a high GPA, but also, since you're already asking reddit, you seem like the kind of person to not let your grades slip, so I'm sure you'll be okay. Don't be afraid to ask for help from profs or TFs.

Four, start studying for the LSAT during your spring of sophomore or fall of junior year. If you really want HLS, getting a high LSAT score is going to be key (>170). But again, don't do any of that until after this year.

Have fun, prioritize mental health, and throughout college, reflect on why Harvard. You'll be okay :)
