We're so wrapped up with egotistical things, career, family, having enough money, meeting the mortgage, getting a new car, fixing the radiator when it breaks-we're involved in trillions of little acts just to keep going. So we don't get into the habit of standing back and looking at our lives and saying, Is this all? Is this all I want? Is something missing?

When you buy a gallon of gas over 60 percent of the energy you pay for goes out the radiator in the form of waste heat? That's why you have a radiator in your car in the first place.
