Your comment is a sign that you should write more lisp, not less. After you've written enough lisp, you may go back to other languages but then you'll really know why you use those.

There are essentially 2 possibilities:

- you need huge or specialized libs not available elsewhere: Python, Java, etc.

- you need extreme speed, binary size or memory control: C, Rust, etc.

For everything else, lisp will be better.
