I think cigarette addicts can quit if they really have a consistent intention, because as far as I know smokers who have been said to be addicted they will not be easy to stop smoking But you are right in saying that quitting smoking might save money, because what I know is that someone who has smoked does not look at the price of the cigarettes they like, as long as they still smoke they will buy them even in difficult circumstances.
I also doubt they can quit smoking by just watching motivational speeches, in my opinion motivational speeches are more directed towards entrepreneurship, but if for smoking I think there must be a desire from yourself first And quitting gambling also in my opinion can benefit us from health, because of course everyone knows smoking is damaging to health, especially with our lungs.
Indeed, the first thing is the desire of a smoker, but it is not easy for them to implement their desires if they are addicted to smoking.
It is true that any motivation or theory will not be able to make someone stop smoking unless they themselves start with strong intentions.
It is very difficult for someone who is a cigarette addict to stop even though they are aware of the losses they get from smoking, which is quite surprising to me.
