Ask HN: What languages should I laser focus on?

I've been recently obsessed with John Carmack's legendary status as a programmer. As I've read more about him and how to achieve some similar success, many people have suggested laser focusing specific technology, and this also includes language.

I've decided to focus on three languages in this order:

* C++

* Swift

* Python

Is three languages too many? If so, what would you laser focus on? I know the answer depends on what technology you want to be good at (and also timing), but I want to hear what HN thinks.
