Depending on what type of language you're talking about, I started learning Korean about a week ago. It's been going pretty well so far. It's not too complicated and I've been able to search online for clarification on things that I have found confusing so far. There are also forums out there just to help you, or to get you in touch with someone who speaks the language.
If you're talking programming language, pretty easy to learn online or from videos. You don't need a teacher and there are many places where you can ask your questions.
