I wrote this in response to a fellow INTJ commenter having a hard time in high school and looking for general advice just now and I figured I'd share in case there are some similar, but quiet INTJs out there this might help. Got any other advice? Please do share it in the comments.

TL;DR: My advice: Look at the big picture and check that your focus is on taking care of yourself.

It depends on what sort of problems you're having as far as the right direct action goes. If the issue isn't anything in particular, just that you're having a rough time, my go-to approach is to zoom out and look at the big picture.

1. You'll graduate and whether you interact with anyone from HS again in your entire life is up to you for the most part. The next stage of your life will be up to you. So you can think instead about what you want to do and who you want to be in the next phase of your life. Plan out what you need to do now so that you can achieve that.
2. What's the worst that could happen? If you're worrying a lot about something and the consequences of it going badly won't matter in a few years, realize that, accept it, and it can improve your outlook and ease the anxiety.

If it's grades, worrying too much won't help you. Maybe the #1 best thing you can do, is sleep - uninterrupted 8 hours, every night. Sleep is when your body repairs and that can be achieved with even just naps here and there mostly, but your brain needs that uninterrupted REM sleep to repair itself and to commit what you've learned to memory. No cramming before tests - that's shooting yourself in the foot. You get a full night's sleep after you study and you'll retain it much better. Tack on even a little exercise every other day or so and good nutrition and you might be amazed at how much easier "everything" is (performance, managing stress, mood, etc.) There are lots of white papers you can look up if you have a scholarly interest, but this TED talk is more fun:

If it's about sex and you're male, my advice may not fit everyone but I wish I could've gone back in time to tell my teen self this: accept that the kind of partners you want probably aren't interested in HS before senior year or after HS entirely. Accept that and commit yourself not to pursue anyone unless they express interest in you first. It's just too natural to want more than they'll be interested in and you set yourself up for disappointment and angst you don't need atm. Besides, when you're busy building a better you, you tend to attract more interest anyway and it'll set you up nicely for the next phase of your life. (Anyone with advice for females on this front, please advise!)

If it's social, see 1) and 2).

If it's depression or other potential mental illness, reach out for help (counselors, relatives, anonymous help lines - whoever you think might best able to understand) even though it might be hard to do so.

I found this article summed up some specific issues INTJs faced as kids (several I remember vividly) in general too:

Did I miss something big? Got an anecdote that'll hit home? I probably don't need to say it, but feel free to chime in and please keep it constructive. 👍
