I started on Debian with XFCE. I figured if there were so many distros based on Debian, then I might as well just use that so I’d be able to configure things myself and learn more about how the OS works.
Anyway, you know the section in the Debian wiki called DontBreakDebian? I did not follow that advice. It went poorly. I’ve since learned from my (many) mistakes and have been running Fedora KDE for a while now.
