Is there one particular quitting philosophy on which everyone can agree? Of course not. But there are a few things that those who have successfully quit have in common, in their quitting experience.
First of all, read the above again. Do you agree with the statement? If so, go ahead and think about what the variety of successful quitters might have in common.
One thing would be that each has some sort of idea about how they managed to quit, and most likely have an opinion about why they didn’t fail to quit as they had in previous attempts. This commonality to me falls under the category of “belief”. This is what the former smoker believes about how it was that they became a nonsmoker.
