It is said. No! There are many ways: e.g. ask the other fellows to fine you 2 rupees for breaking any positive attitude rule. He will fine you obviously but will not do it himself.For example, if your father criticizes you every time and every moment. You obviously can’t preach him against this habit. Now, ask him to catch you criticizing others and for this he can fine you 2 rupees each time. Now, make sure he catches you a couple of times and also be ready to give cash instantly and admit your mistakes promptly and emphatically. Your father will check you but will himself become conscious.
