Forced use of Ni?

I'm a high school student finishing school. All my childhood life I planned how I would start an adult. I planned exactly how I would achieve my desires. I've been planning a lot.

I have always been surprised by my peers, who even now do not know what they will do next. I always knew that if I didn't have a clear and realistic plan to leave and start all over again, then I would live badly. My parents will make me study in an uninteresting place, work in a stupid and low-paid job, or just sit at home and watch TV shows all my life. My wishes won't come true if I don't figure out how to achieve them.

But it seems in ordinary life I don't think so much about the consequences and all that. I am very fixated on my plans, but what if this is not due to my personality, but to circumstances? Or is it still the fact that I do it at all, unlike many other peers, at least gives me Nothing in the stack? In general, what do you think?
