[范文]
Bad habits start growing on almost every one of us without being noticed. Once we realize the bad habits or once they are pointed out to us, it is a wise decision that we get rid of them immediately. But to get rid of a bad habit is not as easy a thing as we sometimes think. Here is how:
To get rid of a bad habit, it is important that we first get to know how harmful the habit really is. Take the habit of smoking as an example. Obviously, smoking is harmful to one＇s health. It can result in lung cancer and heart attack. Besides, smoking is awasteof money. A heavy smoker spends almost as much money a day as he pays for his own meals. So if he can realize the danger and waste, it is likely that he may stop smoking at once.
To get rid of a bad habit, it is essential that we also have a strong will. Let＇s again take the habit of smoking for example. Many smokers pick up the habit again soon after they give it up. A lot of them cannot tell how many times they have attempted to give up smoking and how many times they have failed to do so. Therefore, it is impossible to get rid of any bad habit if we change our minds constantly.
Although it is not so easy to get rid of a bad habit, many people have succeeded in doing so, setting us good models. We should learn from these models and go out of our way to do away with our bad habits, whatever it takes.
