Where to go young, ambitious and with brains?

Question

Career in IT

I choose my path. I settled on C++ and Java. Advise where to go, maybe I have wrong assumptions.
In C ++, as I understand it, now they write games and servers for them, and all sorts of highly loaded and productive services.
On Java - Enterprise, mobile applications, backend.
It seems to me that the tasks solved with the help of C++ are more interesting, cooler, and require good mathematical background (for example, Big Data).
It also seems that the tasks in Enterprise are boring, do not require a creative approach. The web is kind of irrelevant. Mobile development - no complex tasks.
On the one hand, I want to work in a young small team of individual developers, in some kind of studio. I think there is less bureaucracy, more freedom.
On the other hand, we need stability and perspectives.
Everything is interesting. But I can not choose a specific direction, I have no experience and outlook. Please open my eyes. Maybe take off my rose-colored glasses.
And how is it necessary? Maybe you need to learn everything? But you can't really learn everything.
I understand that fundamental training in IT (algorithms, operating systems, databases, networks, etc.) is very important. I realized this only after I graduated from high school two months ago.
There are so many interesting things around. And Angular, and Qt, and the Linux kernel. I want to know everything.
Of course, I could try everything a little bit, but it so happened that at the university I spent half the time in my pants, but I could develop. So I can't spray anymore.
Help me please.

- conceive Big Data technologies on Java or other programming paradigms in general.
- I see your ambition and braininess at the Wasserman level.
- here, alas, even such ambition will not help
- And what did you do during the university?)) Once you understood only 2 months after graduation?
- Alas, but there is no specifics. "I want everything at once, ambitious and with brains."
=> If you spent your time at the university and just now decided to learn something, then keep in mind that such smart, ambitious and promising young people are the first to be interviewed.
So you take it and do it, do you like it? you continue, you don’t like it, you change the stack and do it all over again. If you don’t like anything, then I’ll shout corny - it’s not yours. It looks like the whole world is in front of you and you will do what you like. If tomorrow the employer tells you to do "this" on "this", then you won't get anywhere, you will work on the "not serious web" as well.
