Is it a correct career path?

Hello people! :) I'm quite new in the programming world. I'm really interested in programming from the time I found that there's coming a game called Hytale, and I would love to be able to make mods for it. So basically I have a book that should introduce me to c++, and I'm currently learning from it. But I've heard that c++ is just kinda old, and it would be better to start from Python, since it's new and more beginner friendly. For now, I want to learn c++ anyways, then try to master Java as well. My last choices would be Python and Javascript. What do you think people? I'm asking becouse I just feel kinda lost lately. I just want to stick to one programming language and master it, for next 1/2 years at least.
