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.

For those who are poor in happiness, each time is a first time; happiness never becomes a habit.

Personally, I enjoy working about 18 hours a day. Besides the short catnaps I take each day, I average about four to five hours of sleep per night.

Never go to sleep without a request to your subconscious.

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