I want to never smoke again, even though I could if I really wanted to.
I have made a conscious choice to not smoke, and I fully intend to never smoke again. But, if when tomorrow comes it's a really bad day, I could always have a fag to cheer me up, help me get over the argument with my wife, calm me down, help me relax, concentrate, whatever, or just because I want to!
But I won't smoke, because I don't want to smoke any more.
I have given up nothing. I have made a choice to not smoke. That choice can be reversed at any moment. I am not a prisoner or a slave. I'm an adult and I make my own decisions. My decision is to not smoke.
Why is this important?
Many people quitting smoking resign themselves to the fact that they will never be able to smoke again. They burden themselves with the dreadful thought that they have left something important behind, and that life will never be the same again. The truth is that everyone could smoke at some point in the future if they chose to. Those who are successful in their quit choose not to.
The key here is to understand that you are not giving up smoking. You are making a choice to not smoke.
