Clojure is the language that made me "understand Lisp", as originally stated by Eric Raymond and citet by Paul Graham: https://paulgraham.com/avg.html

It seems like a small thing, but Clojure's choice to open up for other types of parentheses made seeing the structure of lisp programs much easier. This helped me understand how code is data and how macros are functions that can transform both code and data.

An important design philosophy (which is also hinted at in the trailer) is "simplicity". Clojure is designed to give you the tools to build simple solutions to the problems that you want to solve. It approaches mutability, which is one of the key sources of complexity in programming, with immutable data structures. It's a really clever way to do functional programming where your data is copied a lot but the copies are lightweight.

I don't write Clojure any more these days. I'm mostly doing Rust. But it is true what Eric Raymond said: Lisp has made me a better programmer.
