I have been smoking going on three years now, and I at most smoke about a pack a week. Then again I smoke the strongest fullest flavor that I can get my hands on so snaking more than three a day will have your lungs hating you. I have quite more than once, not because I said I was going to quit, I just didn't feel like smoking and wouldn't buy a pack for ages except the rare occasion that a friend from school would share one when we were out a break, but this was only like 2 or three times.
I took an anxiety class and found out why cigarettes can be so addicting. They talked about meditation and deep breathing and how relaxation from deep breathing comes from the exhale, which is the most concentrated act while smoking. It becomes difficult doing the seams breathing without a smoke because you don't get the same feedback from clean air as you do from smoke. That and a cigarette gives you something do do physically, to keep you occupied when you are doing menial things like socializing or just sitting in your backyard to yourself, which would normally be boring after a few minutes, because fairly enjoyable when you have a cigarette in your hands, occupying yourself physically while you keep your brain occupied on whatever you are thinking about.
The trick if you really want to quit is to find other things that satisfy you that give you something menial to do with your hands, for me thats drinking something, water, juice, soda, beer, what have you, and having small snacks if you are around the house. When I am out in public I only go out when I have something important to do so I am always occupied and trying to get shit doesn't to even think about smoking, and between all of that, has been the reason that I have quit more than once without even realizing it. One day I will think, "there is something that I haven't done in awhile" and then later on it will hit me that I haven't had a smoke for some time, usually a week or two, then something will come along and I will want one and it breaks the cycle, but I don't turn around and start chain smoking after that either. I have never really cared to quit nor have I tried, because considering how easy I can forget about smoking and not knowing, very simple will power can get it completely, but in my case because I am not really "addicted" even two months of not having a single smoke, I still can crave one just as hard as I do when I am smoking, so it can become a lifelong battle in that respect.
I recommend you try weaning yourself down a bit, like get some stronger flavored tobacco, try to occupy yourself, and give yourself small menial things to do, maybe even invest in an electric cigarette or even a hookah and have a tradition to smoke that as a social get together occasionally. If you can replace cigarettes with something very similar but much safer especially electric cigarettes, then do it, that with normal exercise, your desire to smoke will decrease the healthier you are.
but still, try to make it as concrete as possible. And then, find something beneficial and long lasting to replace the smoking. As was mentioned, running, cycling etc.
but it's just a matter of preference
