I have fucked up my computer so many times.
- Accidentally uninstalled the graphical environment, because i didn't notice my package manager was asking me if i wanted to uninstall 200 packages, along with whatever i actually wanted to uninstall.
- Tested a fork bomb (it worked!)
- Installed a dual boot system incorrectly.
- Installed a dual boot system correctly, but Windows had an update.
- Tried to switch out a working component with Something Really Cool™
- I have spent days troubleshooting an issue that turned out to be a simple syntax error.
- And, while technically not fucking with the computer itself, this deserves a mention; Fucking up the wifi/network SO MANY TIMES.
I have also succeeded with some really cool stuff, but that's the thing about working with computers; you fail completely, until it works perfectly. This is of course a gross simplification, but it also has a lot of truth to it. There's just not a lot "this is not great, but it will do", it either functions or it fails (until you get it working and start fine tuning it for the rest of you life)
Just laugh at the absurdity of the situation when you realize you were just missing a comma in a JSON file, and don't let it bother you that you didn't notice before you paid to have your second floor covered in aluminium foil trying to fix the issue.
Try creating a VM in GNOME Boxes (if you use GNOME) or Virt-manager, take a snapshot, so you can easily repeat this process, and break it. Just make it stop functioning. Do it in an interesting way, and look up more ways on the internet.
Be curious, have fun and don't feel bad about getting sick of that stupid computer, you can come back later and it won't care that you even left.
