After all those, I found Python, as the saying goes, really does "fit your brain" [1]. Since discovering Python 18 years ago, I have looked at Haskell, successfully avoided Java, and promised myself to "one day" do more JS. Still, Python remains 95% of what I do, and I don't see a problem with that :)
[1] "Python fits your brain" was the theme of the 9th International Python Convention in 2001.
For me, I find using python is like touching both data and code with my hands.
As much as it's trendy to bash Object Oriented languages, the way python allows to lookup all variables and method on a class or an object makes it like using your hands:
dir(MyClass) help(MyClass) dir(my_object) help(my_object)
etc...

I have looked at LISPs, but it's difficult to pick one to invest time in. Because I am so restricted on time I have to stick to languages which are used in the industry (so my fun has real-life ROI), which I think boils down to CL which is often touted as old-fashion and its market seems to shrink slowly, and Clojure which means the JVM and mainly Java libraries and high mem requirements.
For pure fun and practicality, Racket does seem up on the "list", but not used at all in the industry. A lot of languages (Python, Rust) are adopting the good parts of lisp (except for the minimal syntax, sadly), and I'm getting better mileage from spending time learning and becoming better at those than starting from scratch in a language that I won't be able to use during work hours.
That's a perfect summary of my feeling towards it, too. If the PSF puts up a GoFundMe for sending Guido on a nice vacation of his choosing, I will be happy to chip in a few bucks. Same goes for Linus when he hands over the reins, and a few other maintainers who probably cannot be adequately compensated for the impact of their work.
