My seven year old son John, is one of the hardest workers I know. While many of his friends go home to video games or TV, he hops off the bus to do chores.
In our house each family member is expected to contribute. I believe that this teaches responsibility, self-discipline, self-restraint, and instills a strong work ethic. When hard work has always been a part of your life, one is more likely to continue to work hard no matter what the job so you can pay the bills. It's OK to sweat a little to be a contributing member of society.
John has learned that the chickens lay more eggs when they are properly cared for. He enjoys going out and feeding the cow. Tonight he helped Nathan stack wood by the house. He doesn't get paid to help, that's why it's called helping. Best of all, he doesn't expect anything in return. I will of course treat him to some hot coco and a cookie or two.
