I have to agree with jaeusm, you should learn what interests you.
Firstly you should decide what it is you want to gain from learning how to program and what goals you want to achieve. There is no point in just learning how to program for the sake of it, or because you think it'll get you a well paid job at the end.
Decide what it is you want to do with your programming knowledge, and once you decide that, choosing what language to learn will become a lot easier.
For example, if you want to write games, C/C++ is probably the language for you. If you want to get into the web design industry, then learn languages suited to those environments such as JavaScript, PHP, etc.
Decide what you want, before deciding how to get it.
