""" Point eight is enough. In fact I've concluded that it's really a good thing for people not to be 100% happy. I've started to live in accordance with a philosophy that can be summed up in the phrase "Point eight is enough," meaning "0.8 is enough." You might remember the TV show from the 70s called "Eight is Enough," about a family with eight children. That's the source of my new motto. I don't know that 0.8 is the right number, but I do believe that when I'm not feeling 100% happy, I shouldn't feel guilty or angry, or think that anything unusual is occurring. I shouldn't set 100% as the norm, without which there must be something wrong. Instead, I might just as well wait a little while, and I'll feel better. I won't make any important decisions about my life at a time when I'm feeling less than normally good. In a sense I tend now to suspect that it was necessary to leave the Garden of Eden. Imagine a world where people are in a state of euphoria all the time — being high on heroin, say. They'd have no incentive to do anything. What would get done? What would happen? The whole world would soon collapse. It seems like intelligent design when everybody's set point is somewhere less than 100%." """ -- Don Knuth
