In a similar vein I "stopped drinking" 18 months ago with no set goal for how long (but one year was a desirable milestone) and I sometimes say I "quit drinking" but really it's more about deciding not to do it for a while and then not deciding to do it again. Maybe I will some day but I actually don't desire it right now and I do like having this long time period "18 months no alcohol" so if I drank it would reset that. Which some day may be fine, but it's nice for now. I also quit smoking in my 20's. I succeeded by focusing on how physically bad a cigarette made me feel. There was some kind of tobacco buzz but also an obvious depressant effect and it made me feel like shit. During the period I was quitting I would sometimes smoke a little more to make myself feel physically worse so that I would be reminded of this bad feeling and want to avoid it. It worked!
