Being attractive to other people is no doubt a good boost to our esteem or even just looking cool is good enough (that is why we smoke as well) but the thing is, at the end of the day what matters is how we really feel about ourselves, what I've always reffered to as SELF-CONFIRMATION. Never mind what others say, we only have to answer to ourselves. F-ck alcohol! ^_^
