Whenever I start to do something in a hurry and I know I'm being less careful than I should, I remember a story I read somewhere about a carpenter who hadn't properly squared a wall in the house he was building. He decided to just move on without pulling the wall apart and fixing it, but as he tried to continue building the house the mistake kept getting magnified with each workaround he had to invent to try to compensate and he finally had to take apart all the progress he had made to get back to the wall he'd made the mistake on and get it properly squared. It cost him days of work instead of a few hours.

It's amazing how often not being meticulous about our tasks can come back to haunt us!
