If you ask any successful ex-smoker who has quit for a year or more how much of their success they attribute to luck, would you be surprised to know that luck played zero percent?
Luck is chance. It can go either way. It's out of your control.
Is that what you would base your quit upon?
If so, you may as well flip a coin and then do what you want anyway.
You Control This! You Don't Let It Control You. That's How It Works!
I wish you determination and success, no luck involved.
