I can empathise - when I started out I was all about clever code. But the older I get, and the more code I have to deal with, the more I value simplicity.
The 80 character limit is a really good signal that my code is too complex and needs simplifying. The most common occurrence these days is when I have too many arguments to a function, and either need to curry it or create an options data struct. My code is cleaner for this.
And there have been many, many, times that a comment from past me to 3-months-later me has saved me an hour of reading. Code, even intentionally simple code, is not as self-documenting as it appears to be when we're writing it.
