Whats the best way to quit smoking?

I found out that the best way to quit smoking is to put yourself in a situation where you can't smoke, so you realize that you don't really need it. I usually go camping with my friends twice a year or so, and when I went two months ago I forgot my packs, so I just accepted that I was not smoking for a week. When I came back home I didn't feel the need of smoking. I haven't smoke since then
