My daughter responded to "be yourself" with "how can I be myself if I don't know who I am?". Kids are still becoming themselves, so that advice is not actionable.

I agree with the rest of your comment.

I would say that every kid should be exposed to enough experiences to support their natural human quest to understand themselves. But there are people who don't have much capacity or desire for introspection, so that breaks down quickly.

I don't think every kid needs the same things. Which is why the industrial education system fails for most. There is no perfect curriculum, there is no perfect law, etc.
