I originally had a variation of this post in the The Teaching of Conventional Wisdom at Freedom thread at Freedom. It was prompted when a member on the board wrote to another member that he or she should do what ever it takes to quit smoking. The example specifically given was drink water or eat ice cream. I have to say, if someone plans on going the ice cream route they had better be ready to go buy a whole slew of complete wardrobes, of ever increasing sizes. If your crutch for smoking thoughts are going to be any high caloric food weight gain of massive amounts should be expected.
As far as using "whatever it takes," I guess that can be translated to taking any food, any drug, legal or illegal, or participate in any activity, no matter how ludicrous or dangerous that activity might be. Does the comment smoke crack cocaine, or shoot up heroin, or drink as much alcohol as it takes, or administer lethal dosages of arsenic or cyanide make any sense to anyone as practical advice to quit smoking? If not, the comment of do whatever it takes loses any real concept of credibility.
As far as quitting smoking goes, the advice should not be "do whatever it takes to quit smoking," but rather, "do what it takes to quit smoking." What it takes to quit smoking is simply sticking to your commitment to never take another puff!
