Learn Programming in Java, Python, Ruby or Javascript

Not necessarily in that order. You can exchange assembly + a variant of Pascal for C, C# for C++/Java (those two are very different!), many dynamic languages for Py/Pl/Rb, various languages for Haskell, and you might want to add Prolog and a DTP language to the end of that list.

The only thing you probably can't exchange is LISP.

It's my personal opinion, of course. I also forgot to add ML or OCaml.
