When trying something is a lose-lose situation

I was telling the boys today how I have never smoked a cigarette (seriously!). I asked them to guess why and they had several good reasons, but didn't really guess the gist of the matter. I never did it because I felt it was a lose-lose proposition. Suppose I smoke a cigarette and like it. Now I have something that I like but that I know I shouldn't do because it hurts me. Not a good place to be... On the other hand what if I try it and don't like it? That is not a great outcome either right? With hindsight I think most of us would skip the things that we try and didn't enjoy. Better to leave cigarettes alone!
