The sooner we associate long hours and multitasking with incompetence and carelessness the better. The next time you hear boasts of executives pulling an all-nighter or holding conference calls in their cars, be sure to offer your condolences; it's grim being stuck in sweatshops run by managers too ignorant to understand productivity and risk. Working people like this is as smart as running your factory without maintenance. In manufacturing and engineering businesses, everyone learns that the top priority is asset integrity: protecting the machinery on which the business depends. In knowledge-based economies, that machinery is the mind.
