This is an interesting article, but I think it is heavily skewed toward the author’s goals in life and who they innately are. A guide for a more introverted person, or sports-oriented person, or highly social person would be vastly different.
In particular, I think the author makes the mistake of believing everyone must be a creator. The reality is most people aren’t good at it, don’t like it and don’t pursue it. And that is OK.
It also underestimates how young 14 really is, and how much still needs to be learned in general, not just in school but in life.
The difference between 14 and 18 is a vast chasm.
