    To get rid of a bad habit, we should first get to know how bad it really is. Let's take the habit of smoking as an example. It is a waste of money. A heavy smoker spends almost as much money a day as he pays for his own meals. Besides, smoking is also harmful to one's health. It can result in lung cancer and heart attack. People who can realize this will stop spending money damaging his health.
    To get rid of a bad habit, we should also have courage and a strong will. Let's again take the habit of smoking as an example.

So it is impossible to get rid of any bad habit if you don't have a strong determination.
    However, no matter how difficult it is, we should never give up doing away with bad habits. In fact, many people succeed in giving up their bad habit Once we are aware of the bad habit, we should never find any excuse, instead, we should do away with it with a strong determination.
