I picked up the skill from my granddad when I was a kid. Yeah, 6 year old with a soldering iron, what could go wrong, right? Welcome to eastern Europe. There are really 2 things: good soldering iron(and soldering helping hands kit) and practice. Which takes me to one of my hobbies: drones. Look up a kit called Diatone Mamba soldering practice board. They cost 2-3 bucks, get 10 and you'll get the hang of it in a few hours. Oh and a fume extractor(any old pc fan will do).
