There is nothing to give up. There are only marvelous positive gains to achieve.
Never see the odd cigarette. It doesn't exist. There is only a lifetime of filth and disease.
There is nothing different about you. Any smoker can find it easy to stop.
This is why casual smokers are effectively more hooked than heavy smokers. Not only is the illusion of pleasure greater, but they have less incentive to quit because they spend less money and are less vulnerable to the health risks.
All you ever enjoy in a cigarette is the ending of the craving for it, whether it be the almost imperceptible physical craving for nicotine or the mental torture caused by not being allowed to scratch the itch. Cigarettes themselves are filth and poison.
While you are smoking that last cigarette, be conscious of the bad smell and taste and think how marvelous it will be when you allow yourself to stop doing it.
