I'm currently reading Zero to One by Peter Thiel. Here is one thing interesting he mentions.
To grow, one can either scale vertically or horizontally (paraphrased).
Now if we apply this to your situation , scaling horizontally would be learning new languages, ie. Objective-C, Javascript etc. I'm assuming you're not really about this but you want to scale vertically.
If scaling vertically is the case, then what you really want to focus on is doing something either 1) other people have not done before yet and/or 2) do something that is 10x better than what is already out there. I don't do too much C/C++ dev but maybe think about embedded, OS, GPU, etc.
If you accomplish 1) and/or 2), then you can truly master C/C++ dev. My 2 cents.
