Once you decide, you simply make up your mind you won't smoke NO MATTER WHAT. Prepare ahead of time what you will do if life throws you a curve (and doesn't it usually?) Will you take slow, deep breaths, march in place, call a friend, blog here for help? Have a PLAN!
There are three keys to success at this: Preparation, planning and commitment.
It really is that simple. You make the decision, then a plan, and commit to the effort 100%. It isn't easy, but it is oh so doable.
