He never seems to learn

I have this friend who seems to never learn from his mistakes. I swear that every time something is broken in his house, he thinks he can fix it! When he was younger he loved to take things apart just to see how they worked. When he was a little older, he tried to fix a broken toaster once. It didn’t work of course even though he worked on it for hours on end. When he got a place of his own, whenever the HVAC system would break down, he would always attempt to work on it. Every single time he did this, he ended up causing damage to the system. When he would end up calling the HVAC company to take care of the problem, the HVAC technicians would always complain that he caused a great deal of damage to the system, and they would charge him a lot of money for the repairs. Recently when the HVAC broke down again, he went right at it feeling confident that he could repair the system. I reminded him that he had done this many times before and failed… He said he had been studying a lot about repairing the HVAC system, and he felt confident he could succeed this time. I just sighed and let him mutilate his system. Well, when he was done working on it, I was actually surprised when the cooling system actually engaged and seemed to work fine. He said, “How do you like that?” I was surprised that he got the system to work and congratulated him for the fix. Of course, a few hours later, the system failed again…
