Once upon a time I was exploring different linux distros on a monthly basis. It was magical to me that you could even switch between compatible desktop environments on the same installation.
Eventually I found a desktop environment that worked wonders for me and my workflow. But since I wanted to keep exploring I wondered if I could install a desktop environment that was "incompatible" with the flavours I was using. I think KDE installations aren't compatible with GTK distros or something like that. I was throughly within the woods of desktop environments, where the tutorials on how to do the installation required imagination, and I was loving it. Only to discover that I wasn't skilled enough to not completely rekt my laptop with yet another attempt to fly too close to the sun.
Wrecking the laptop is not an issue... It actually taught me more about how computers work then anything else. The first computer I recked was originally running windows 98 and I deleted files in the system32 folder to make space for a few more Kanye and Common albums on the hard drive, don't delete system32. I managed to get a copy of Windows XP SP3 installed to fix it and eventually got a bigger hard drive because Kanye was in his prime and I had to dissect the releases.
The big issue I had with wrecking my linux laptop was that I don't remember the name of my preferred flavour of linux desktop environment because I was in the very fringe distros at that point. One day when I'm not too lazy I'll probably search for it again.
