I'm not a technician, but sometimes I start inventing and fixing things at home. Sometimes I end up damaging them even more hahaha.
I have to buy a soldering iron, it got damaged, I need to make several things, but without it I can't start inventing. I have to fix an old TV. I have a small video game console, but the charger got damaged, I don't have to fix anything, just look for the charger and buy it.
Sometimes I watch tutorials on youtube to learn on my own.
