What to learn in programming so as not to regret the choice later?

Question

Programming languages

Now concentrated on php+js. As if I have no work experience, experience working on projects, but I already know a lot of things. What I don’t choose, then dofiga there are already people like me, then there is no prospect. The question is clear I think.

Answer 1

everywhere/always there is someone better than you. you don't need to be the best (although you should strive for this), it is enough to be better than the majority.
and this, alas, does not depend in any way on the ap or the sphere.

Answer 2

I will add to the absolutely correct DevMan answer :
Learn:
1. How to build the project architecture (and only then - the code),
2. Algorithms: what and in what situations to apply them.
3. Means for working with information provided by factory production: how and what is on the market, how and what works, what is contained inside (CPU / GPU / etc. architectures), etc.

Answer 3

Don't learn anything

I already know a lot

it seems to you
Where there is no one - no one will pay
