This is definitely a good one.
We rationalized smoking so well didn't we? We knew it was ruining our health, would cripple and eventually kill us, yet we puffed away. Gotta die from something right? Yeah, right. Although this is true, we're all going to die and we'll die from something but does it have to be 20-30 years early?
Rationalize your quit until you know the truth about smoking. If we rationalized years of smoking knowing the how bad it was for us, why not rationalize quitting knowing how much good it's doing for us?
One thing we're all very good at is lying to ourselves. It's innate and there is nothing we can do to change it. We believe we're good drivers when we could be horrible drivers. We think we have a really good sense of humor when in fact we may not (shut up, Ava :)), think we're good cooks and the list can go on and on. My point is that we can do anything that we put our minds to and are capable of convincing ourselves of just about anything. We convinced ourselves that smoking benefited us in some way when in fact it did not.
Use those veteran rationalization skills that you've honed over most likely several years or decades and rationalize your quit and never take another puff.
