You can quit, it takes effort, patience, and a bit of courage. If you think quitting smoking is difficult, try being this guy. Do you think he succeeded right away? I'm guessing he's done this a few times. Many can and have quit successfully the first time, many others have not, but if you keep at it you will get it eventually, just like changing a tire with no hands!
