Well, "Just do it" isn't "Do it the right way".

Learning just enough of a language or a framework to patch up a solution to a specific problem doesn't take very long. It takes a bit of experience, but it doesn't take a mythical hyper-productive hacker. The solution might not be pretty, and it probably won't scale to millions of users or stay solid for decades, but it will solve the problem. And in many cases, it's all that matters.
