The most honest recommendation I can give you right now - a resource that I myself have found just recently. I soon turn 19 and I sooo wish I had found this shit much earlier. This is good for anyone on BHW too, not just youngsters. And I want to stress that I'm not promoting this in any way, I've genuinely found it extremely good. I really feel like a lot of times we on bhw give pretty generic advice (of course not everybody). So this is why I want to take the chance and share a very specific resource that I'm sure you won't regret checking out.
It doesn't matter that their name is cheesy as fuck. The information is good and no BS.
Read this blog. Look at the top posts and beyond:

I also highly recommend their ebook "Efficiency". You don't have to buy it, you can easily find it on b-ok.cc; I have started reading it a few days ago and I'm already making big changes to how I think and work.
