Maybe I don't have the most room to talk, being as this is my resolution too, but...
Ive tried to quit before, and a lot of it is mind power. Here's a scenario:
Your standing there, debating whether you should bum a cigarette. At first thought, you make think "oh, just one wont hurt" or "I'll just try again tomorrow" Now, realistically,you must force yourself to not want to smoke. More accurately, you have to create reasons that will force you to decide against it.
Think about it. Your about to mess up over one cigarette. But why? First off, whats so great about that one cigarette? Being a smoker is tons of fun, but just one cigarette is nothing. When you sit down to smoke it, are you constantly thinking about how great the cigarette is? Or how much you enjoy it?
No, your mind is probably wondering off while your subconcious is enjoying it. It will be cool for 5 mins, but after that you will just want another...and another. Also, you'll sit and debate wither you actually want to smoke for about half an hour, until you break down and you get what? 5 minutes of satisfaction.
Think about what your parents, friends, and family think when you tell them your gonna quit, but then still smoke. You don't want them to think of you as weak do you? No, stay strong and prove to them and yourself that you have what it takes.
And lastly...How many times have you told yourself that your quitting? But you haven't. I say screw that and actually do it. Every week "oh, im gonna quit. I'm gonna get healthy" but it never happens. Well F'ing make it happen. Don't try, just do! And especially with PV's...its like failing a math test when the answers are written on your arm.
PS: None of this was based towards you, this is just what I try to think to psych myself out. I feel like a hippocrit considering ive been off the annys for only 4 hours (woke up and quit this morning) but these thoughts are the ones that wont make you not smoke, but make you not really want to smoke.
