A supervisor once told me my wire routing was 'a mess waiting to happen'
I was working on a Cessna 172's avionics panel about 6 months ago, and I thought my zip-tie work was neat enough. My lead pulled me aside and said, 'You're pinching bundles and creating stress points. That's a chafe risk in 500 hours.' He showed me how to use proper clamps and leave service loops. I changed my whole approach, and now I plan the run before I even pick up a tie. Has anyone else had a piece of simple, blunt feedback that completely changed a routine task for you?
