A teacher, whose second graders continually got up from their chairs, was instructed to tell them three times a minute, to sit down. The children continued moving around. She affirmed their good behavior and praised the projects they were working on. Smoking is bad. Gaining weight is bad.
Wrinkles are bad.
The list is endless. When I am around people who smoke, I often hear remarks about how harmful it is for their health. If it bothers you that somebody smokes, certainly say so, but after that, drop it. If enough people think smoking effects health, it will. Some thoughts keep repeatedly popping up, often at moments when we are tired, depressed or under stress.
