Learning to code in 2017 - Is it even worth it?

So I've thought that I'll be learning to code in a few languages.

I have started learning HTML, HTML5 and I'm thinking of learning JavaScript , CSS to completely be able to program in HTML .
After I have learned all that, I'd start PHP and mySQL .
So that's six programming languages. SIX!
How much time do you think it will take to master them all?
If we consider the 10000 hour rule, then the answer is a lot.
And that got me thinking if it's even worth the time and effort.
What do you guys think?
