121 Kick the Habit

　　There are millions of people all over the world who smoke. Most of these smokers¹ have tried to quit smoking at least once in their lives， but in vain. Make no mistake； smoking is addictive². And once you are addicted³， it's very difficult to stop smoking. Many people have tried many different ways to kick the habit. None of them is easy.

　　Take a tip from me. I smoked for twenty-five years. Then one day， I decided⁴ to quit cold turkey after trying everything else. It worked. That was two years ago and I haven's smoked a single cigarette since then. Good luck！
