I often find myself reading up on a language/technology that I probably will never use, and wonder if this pointless learning and whether I should be using my time more effectively?

For example, over the weekend I started reading up on common lisp and the next thing had installed SBCL, Emacs and had started on the Practical Common Lisp book.

I am a graphic designer by trade, and am still getting a handle on Ruby and JavaScript, so my concern is that the time I spent investigating Lisp could be better used learning more about these languages and working on personal projects I already have underway using them.

Or is any learning beneficial and having a curiosity about other languages healthy?
