If the Lisp way of thinking about and solving problems is a good fit for you, then you should learn it because it will make you happier and more productive. If not, then don't bother.
That's a Catch-22, of course. How will you know if it's a good fit for you unless you learn it?
So that reduces the decision to: if you are curious whether Lisp is a good fit for you, learn enough of it to find out. If you're not curious about that, don't bother.
But you might want a preview of what things make it a good fit for some people. Lisp in general, and Common Lisp in particular, is a good fit for me because its default mode of operation is to start the Lisp running and teach it by interacting with it expression-by-expression how to be the program I want to build. Common Lisp is consciously designed to work this way, and provides a host of well-designed conveniences for it. It turns out that working that way makes me happier and more productive than working any other way, so it's my favorite programming language.
Not very many other programming languages work that way, but to be fair, some do. Examples of some that do are Smalltalk, FORTH, and Factor.
Some languages and implementations provide more support than others for that style of work. The most comprehensive support for it is to be found in Common Lisp and Smalltalk implementations.
If that sounds interesting, then it's probably worth your time to learn Lisp (or one of the other languages I mentioned). If not, then I wouldn't worry about it.
