I have a couple friends that are trying to learn how to program and they are constantly bouncing from java to python to javascript to whatever else, and it really does them no good because they never sit long enough to learn the fundamentals of programming, just the basics of that given language. You really do have to work with one language for awhile and get comfortable with that language/environment and how to use it to solve problems. Once you get decent at this, then bouncing to the language du-jour is easier, more enjoyable, and you take away a lot more from it ('oh wow cool, in language X I had to do this, this, this and that, with language Y I just have to do this!')
