Check how many service calls come from sloppy installs. I fixed a mess last month where unlabeled cables caused a full day outage. The customer paid double for the emergency fix. If the first tech had bundled and tagged, it would have been a 30 minute job. That lost time and money hurts your company's name. Doing it right the first time keeps clients from switching to competitors.

My friend Dan did that once and literally fell asleep at a red light. Totally get what @stellachen means about the zombie thing, it's real. He had to switch to only shooting when he had zero plans the next day.

My friend had this beautiful blue vase she kept messing up, the base was always lopsided. She was about to trash the whole project when I noticed her cat's hair was stuck in her wax, like a bunch of it. She'd been working near where the cat sleeps. We picked it all out, and her next try was totally straight. She never even thought to check for that. What weird thing has messed up your work without you knowing?
