You may have decided again and again, and again and again...

You may have decided again and again, and again and again you have failed - not because smoking is such a great phenomenon that you cannot get out of it, but because you are trying from the wrong end. Rather than becoming aware of the whole situation - why you smoke in the first place - rather than becoming aware of the process of smoking, you are simply trying to drop it. It is like pruning the leaves of a tree without cutting the roots.
