I've realized that most of my best ideas have followed a good night's sleep.

Sleep is like a drug. Take too much at a time and it makes you dopey. You lose time and opportunities.

The only time I have problems is when I sleep.

Never go to sleep without a request to your subconscious.

There is plenty of time to sleep in the grave.

The serpent, the king, the tiger, the stinging wasp, the small child, the dog owned by other people, and the fool: these seven ought not to be awakened from sleep.
