These days I work in Emacs, but before then I lived in Vim/Tmux for 2 years. My youth though was never this technical nor was it officially programmatic.
I instead spent my time hacking, tinkering and breaking things.
I spent my time in primary school creating hidden folders1 on my student drive to hide games from my teachers. But even earlier than that, I had a penchant for doing the wrong thing.
