Back in the VIC-20 days, I had the VIC Forth (https://ia800304.us.archive.org/34/items/VIC_Forth_1982_HES/... and https://photobubba.com/wp-content/uploads/2016/06/an-intervi...) cartridge and the book Starting Forth (https://www.forth.com/starting-forth/). It was my second programming language, after BASIC.
Like everything else, it was easy do simple things, much harder to do anything else. My brain also rejected doing stuff with postfix notation.
It always fun trying to explain Forth to developers used to higher level languages. It always came down to "a word is like a function, but not really"
