Interesting; there are many stories about smoking, addiction, and the extreme difficulty to quit. Let's be a bit philosophical: we have both freedom of choice ,and freedom of will.. There is a significant difference.
Freedom of choice: the ability to choose to do what you want at any time i.e. snap your fingers, cross the street kiss your significant other, etc.
Freedom of will is quite different: It is the commitment over a period of time to monitor your trait that you want/need to change, as difficult as it is, or will be. That explanation may be bothersome to many, but it is accurate. This exercise is not easy, or is it supposed to be easy. It is the constant monitoring that makes the difference.
I'm not interested in arguing (also a philosophical use of a word - the posing of premises that are valid - the efficacy of this philosophical position - is what it is.
I offer this essay for I quit when the first of my three sisters passed away from cancer. the benefit of those sincerely looking for a solution, not an excuse. (I am a reformed smoker - the worst kind to discuss this issue).
I wish the best to all of you trying, I know it will not be easy if at all.
Best to all on this Holy day.
