A customer told me my soldering looked like a spider had a seizure
I was fixing a vintage radio for a guy in his 80s, and he watched me reflow a cracked joint on the tuner. When I was done, he squinted and said, 'Son, that looks like a spider had a seizure.' I thought my work was fine, but he was right. I was using too much solder and my iron was too hot, leaving a big, shiny blob. I switched to a finer tip, dropped my temperature by 50 degrees, and started using more flux. Now my joints are small, clean, and actually hold. Has anyone else gotten a piece of feedback that made you change a basic habit you thought was okay?
