Do you want to learn all of those because you have a genuine interest in doing so, or do you want to learn all of those things because you feel you "should"?

I browse HN and read comments and articles I do not even begin to understand, and it's hard not to feel rapidly inferior. But you don't have to be a genius to make a difference, and you don't have to be a genius to be happy.

I make my living off the back of PHP. Sure it's got a bad rep, but it's hard to knock something that keeps a roof over my kid's heads and their bellies full.

If you want to learn because of genuine interest - do one thing at a time. Let your curiosity guide you. And good luck!
