Smoking, goofing off at work or over eating are common habits that people frequently admit they wish to give up. They go on to say that they realize these habits are harmful. Smoking can give you cancer and kill you just as over eating can ruin your health. Goofing off for too long at the job could get you fired. They know these affect them adversely over time. Yet if you ask them why they don’t do something about it, you are likely to get a wide range of excuses varying from “Not now. I am a bit tied up. I want to start in right earnest next week Monday” to “Let me see how far I can last out without having to change”.
