When one buys an automobile that has frequent breakdowns, he says he got a lemon. Children don't come to us as lemons. Parents cultivate them into it by grafting their children into the root of their own unstable souls. There are several great benefits to training. First, but second in importance, the parents are benefited by taking the time to train and be consistent, because in the long-run it will take less time.
Nagging time is slow time.
Each moment is drawn out in stress and anxiety. The gripper and nagger puts in thirty hours a day, where the smiler is always on vacation. I think the aging clock runs faster on people who are always disappointed and anxious. If you want to grow old in a hurry, don't train your children. Develop an adversarial relationship with your children by just waiting for them to irritate you to the breaking point, and then show them you mean business by flying off the handle.
