(It's important for your comment to be worded like that, and not just "you shouldn't learn C++ and game programming at the same time". Otherwise a lot of the context is lost.)

That said, if I had to do it over, I wouldn't change a thing. I know myself, and therefore I know I'd be too timid to try to ever do more than move Python code into C via writing my own extensions. That would have significantly crippled my career, and denied me the opportunity to work on game engines written entirely in C++ (which almost all triple-A game engines are, for better or for worse).

That's a personal failing, I admit. I'm just spewing thoughts that were important relative to my career, because it's the only actual example I know enough to talk about.
