The first text editor I used outside school was Notepad++. It served me really well during my early years, but around 2008 I got my first job, and saw a coworker use vim. I was quite mesmerized to see how efficiently he moved across the files, so I obviously wanted to learn using it as well. I don't think I had any configuration at all initially, whatever the distro configured by default was what I used. I opened my own repository for my vim configs in 2012 September 19, at a quite late time, 3 AM. Apparently even 10 years ago, my most productive hours were after midnight.
