The odds of you quitting smoking with hope and luck as your allies are probably close to the same odds as winning the lottery.
How many times have you done that? Is your bank account full of lottery winnings?
You need to decide you won't smoke anymore.
Then, make a promise to yourself that you won't smoke anymore. Honor the promise.
You can't smoke if you don't have any around.
When you want to smoke say this out loud "I don't do that anymore"
Say it over and over.
People who fail talk themselves into smoking by saying things like "I really want to smoke" or drink themselves stupid.
This is common sense. Use some.
