"When a story has gone the grand circuit, and travels back to us uncontradicted, we may reasonably begin to relax in our belief of it. If nobody questions it, it is manifestly a fiction; if it passes current, it is almost sure to be a counterfeit. The course of truth never yet ran smooth."

Just as important as getting enough sleep is thinking about sleep in the right way. Stop thinking of sleep and naps as “downtime” or as a “waste of time.” Think of them as opportunities for memory consolidation and enhancing the brain circuits that help skill learning. Nor should you feel guilty about sleep. It's just as crucial a part of successful brain work as the actual task itself.
