Good Common Lisp doesn't use lists. A Lisp app does nothing like processing lists; in fact, Common Lisp only uses list-processing for processing source-code (aka macros). It is much more like a faster, more functional Ruby or Python in that it uses classes, looping, but encouraging good functional abstractions. Real-world Common Lisp looks nothing like scheme.

CL is a powerful general purpose language in which you can accomplish much the same things as other programming languages. Where it will really shine is when you benefit from extending the language or environment to suit a domain and then you solve problems of that domain.
