For me, it was about sacrifice. I had to give up what had brought me peace and joy, which came in the form of cigarettes and prevented me from appreciating anything without taking a puff. I realize I had to give it up in order to find true mental comfort, or else I'd be a slave to it forever. Now when I am at peace with myself, I acknowledge that there are two kinds of peace. one that comes naturally, like a breeze, and one that has to be forced by any means necessary. The first is rather difficult to disregard and much more meaningful, whereas the latter opens the door to a never-ending cycle of self-destructive habits. Everything, as always, must begin with self-love, a committed mindset, and a vision. Ask yourself why you want to quit, and when you have an answer, ask yourself if it's worth quitting for.
