Try to learn languages with different paradigms, this will improve your skills in all languages (one language for each paradigm is ok, I'm listing in my order of preference):
"Structured Programming": C, maybe Fortran if you're going to work with numerics
Generic Programming & OO: C++
Script Language: Python, Ruby or Perl; Matlab if you want numerics
Heavy Object Oriented with VM: C#, Java or Smalltalk
Functional Programming: Ocaml, Haskell, Scala
Machine Programming: i686 Assembly
Logic Declarative Programming: Prolog
Database Querying Language: SQL
But also don't rush yourself... learn one language at a time... maybe a new language every year... with this you're going to have a very handy toolbox for any problem you might need to solve ;)

Learning one is not actually useless, well to me. Because it helps to be a master of the language. And also don't forget that in company or organisation everyone is assigned to a particular duty. For instance, web designer takes care of the UX experience and someone with JavaScript experience wouldn't have to worry the head over it or say PHP server-side scripter.
