The myth of pennilessness and the behaviors that follow!

2011- in her monthly news letter, raising happiness, Christine Carter, Ph.D. writes about taking time off: it is a great way to be in life. I am so guilty as charged and have to train myself, a tall order & a difficult task ahead. She notes and I so relate to this:
"I was poisoned by that hypnotic belief, as Wayne Muller writes, that if I didn’t continually push myself, my work would tank and my children and I would be left penniless."

Dr. Carter said: "Here’s what I’ve learned: It is a myth that we succeed through unceasing and tireless effort. Yes, research does find that consistent and deliberate practice leads to elite performance in many fields. But focused work and consistent practice are not the same thing as unending work. Olympic athletes must rest or they get hurt. Fruit trees forced to produce for more than one season lose their ability to bear fruit. And us worker bees can slowly develop sleep debt so deep and burnout so profound that we are left too exhausted to function.

When health problems forced me to dramatically change my work schedule last fall—cutting back 10 hours a week or more—something amazing happened: My productivity actually increased. As a sociologist, I know research shows that rest often does improve productivity. But somehow, I found it very difficult to actually internalize this in my own life; I was poisoned by that hypnotic belief, as Wayne Muller writes, that if I didn’t continually push myself, my work would tank and my children and I would be left penniless."

I am one of those like Wayne Muller wrote, What do you think?
