Set aside half an hour every day to do all your worrying; then take a nap during this period.
~Anonymous

There is more refreshment and stimulation in a nap, even of the briefest, than in all the alcohol ever distilled.
~Publius Ovidius Naso (Ovid: 43 BC – 18 AD)

Sleep is one of the key strategies the brain uses for learning. It’s called consolidation in the research literature. Basically put, your brain needs down time in order to process all that you’ve taken in during the day. Naps can perform the same function.
