What is something you completely regret doing?

Me doing stupid things to my electronics when I was 10, in specific detail:

I took apart two of my computers and had problems reassembling them afterwards to the point where I ended up trashing them. Thankfully I kept most of the parts from them and have managed to restore one of my childhood computers after years of finding the parts I lost/discarded. I took the hard drive out of the other computer and formatted it when I put it in a different computer, I lost a couple years worth of data, which I'm never going to get back (one of them was a video of a skateboarding competition that I went to).

Me not realizing the video card in my computer was dying when my computer used to BSOD on a daily basis. Once it died, I had to use my mom's laptop until my dad was able to get a replacement video card, the tragic part is the replacement video card (an nVidia Geforce FX 5200 128MB AGP video card - one of the worst GPUs of all time according to various sources) was a MAJOR downgrade compared to what it had previously. My embarrassment for having such a crappy graphics card was what lead to me disassembling the computer and breaking the pins off the CPU in the process as well as damaging the computer case. After that debacle, I had to use one of those crappy clamshell Dell Optiplex computers (which were known for having capacitor problems) until I got a better computer several months later.

Me throwing a Hot Wheels car at my TV over missing a part of an episode of the Food Network show Unwrapped. It left a tiny crack on the LCD panel, but luckily it didn't damage it completely as it still worked perfectly aside from having a tiny white speck on the top-center of the screen.

There are a couple more examples that I could list here, but I feel like I've mentioned enough already.

How about cracking your laptop's motherboard while trying to replace the keyboard? I went on to repair hundreds of laptops. Oh yeah I also erased all my childhood drives by accident at least once, but I backed up most of the important stuff. Most...

My biggest regret in life is that I went to the university to study natural science. I am not the person for it and I lost a lot of time in life and have also a lot of debts because of it. I either should had not study at all or at least in agronomics since this was also my job before (I am an educated gardener).

I never regret anything because I think it is useless. If I could go back I would change some decisions in my life, but now I can't change the past. From this it follows that regretting the past is useless.
