I see you got through your first Christmas Eve with you quit intact. Congratulations. That was just one of those things you had to experience to believe it was possible. No matter how many time I told you or thousands of people told you that it could be done, it is only by living through such situations that you really believe in the possibility, or said more accurately, the reality that your life can go on without smoking and everything you did as a smoker you can do as an ex-smoker.
The only reason you lost those earlier quits on past Christmas Eve's is because you took a puff on past Christmas Eve's. You know better now and just recognize that you have the knowledge to survive all future holidays, weddings, funerals, floods, hurricanes, tornados, ship wrecks, acts of terrorism, job losses, promotions, births, anniversaries, hospitalizations, retirements, coronations, inaugurations, elections, political coups, new homes, new cars, automobile accidents, court appearances, jail time, parole, winning lotteries, losing bets, favorite sporting teams winning championships, favorite teams blowing the season, loss of a pet, taxes, graduations, getting straight A's, flunking out of school, suffering the worst embarrassing moments, winning the Noble prize, or experiencing some other major accomplishment that you will reflect on as the proudest moment of your life. Surviving everything is possible with your quit intact as long as you always remember to never take another puff!
