What I find funny is that people's who've quit smoking are as tough on smokers as born-again Christians are on me.
Some are, I'm not.

I don't mind smokers at all, and I don't find the smoke offensive.
I quit, cold turkey.
Most mornings, you wake up, and think, "I want a cigarette". But every now and then, you wake up, you smoked your last cig from the night before, and you need to get a new pack, except something inside you says, "I might quit today"
That's when you try to go 8 more hours before getting a pack, after 8 hours, counting sleep, you are at 16, so if you can push just 8 more hours, it becomes a day, and you can go to sleep, wake up, and you now have quit smoking for more than a day.
After 3 days, the nicotine is gone, and any desire you have for smoking is actually habit.
I have quit for more than 6 months about 3 times. It is just a matter of recognizing one of those mornings you can quit on.
Another trick -- don't tell anyone, until at least a week, even if they ask you, deny you quit, say you are just cutting back or something. Keep it a secret.
That way, you recognize you are still prone to restarting. People who after one day going around saying, "I quit smoking" after one or two days, end up looking silly if a week later they are smoking, and are just annoying if they have done this 20 times in the past year.
Another mind trick -- I can't stand listening to people always talk abut how they are going to quit smoking as they are smoking.

If you are smoking, just enjoy the cigarettes, and try not to think of quitting. I know it's hard, but try to just enjoy the cigarette.
yet another trick - after a week, try to stop counting how long it has been since you quit. It will soon just start to melt away as a distant memory, and one day, you'll be able to look back, and think, "I can't believe I used to smoke all the time, was that even me?"
I don't know how long it's been since I smoked, but I know it's been over a year.
One more thing:
Prepare for the sickness...
after about 2 weeks, you will get sick, and your lungs will start to clean themselves. You will get sick as hell and cough up so much nasty phlegm. But in a way, it feels good, because you'll know your body is cleansing.
Finally, you see a girl 2 months from now, smoking, you want to talk to her, but don't know how....
forget it dude, not worth it, either think of something else to strike up conversation, or don't do it, because you cannot have just one cigarette.
