Just like the old carpenter's adage- - - -"Measure twice, cut once!" Most of the times I've royally messed up a project were when I decided to take a shortcut, or just ignored an obvious flaw in my reasoning because I didn't want to admit I had made a mistake. That kind of thinking can get expensive and embarrassing!
