The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
"I'm selfish, impatient, and a little insecure. I make mistakes, I'm out of control, and at times hard to handle. But if you can't handle me at my worst, then you sure as hell don't deserve me at my best." - Marilyn Monroe
