Force yourself to take a five-minute break after each step, even if you think you don't need it. I learned this after mixing up parts in a console repair and having to start over from scratch. Now I keep a basic checklist on my bench and physically check off each thing before moving on. It feels silly at first, but it beats doing the job twice for free, that's for sure.

Remember rules help people who feel lost with fashion.

Clever workaround for those tight spots. What kind of string did you use, and did it ever break under tension? In my experience, paracord holds up better than regular twine for pulls like that. Your mileage may vary depending on the conduit age and debris inside. Have you had to clean out the conduit first, or did the bolt method clear a path as it went?
