Do it man! Learn whatever you can.

The great thing about programming is often one can take the programming methods they've learned with one language, and apply it to a new one. I'm not talking C++ to ASM, more like C++ to Java.

So it will definitely be tough getting that first language down, there is a lot to learn. It may even seem like too much off the start, but once you learn the concepts, they stick - just like riding a bike!

My suggestion for whichever language you choose, would be to learn Data Types, Variables, Basic Arithmetic, Loops (compounded with arithmitic), functions, arrays, multi-dimension arrays... In that order.

Those are the basics of any programming language. There's much more to learn after the fact, but if you understand those basics, you can apply them to any programming language you understand the syntax with.
