A man approached rabbi and said, "Bars are full of people sitting there to enjoy themselves."Rabbi replied nothing to him. Not getting any response man again said, "Bars are full of bursting people spending all night playing cards drinking beers and you said nothing??""It's good thing that bars are full", replied rabbi. Man was surprised to listen reply but said nothing. Rabbi continued, "Everyone.. since the beginning has always wanted to serve god. the problem is that not everyone knows the best way to do so. just try to think for a minute  what you judge to be a sin can also be seen as a virtue. these people who spend the night in bar awake, they are learning alertness and persistence. when they have perfected these qualities then all they will have to do is turn their eyes to god, and think what excellent servants they will make..!!"Listening to this only thing man said was, "You are indeed an optimist person.""It not about being optimist. it is merely matter of understanding, whatever we do however absurd it seem can lead us to the path, path of god, it's all just question of time..", replied rabbi. 
When ever we feel troubled we think that we should try to change people and their attitude but what we need is to understand that sometimes change need to start with within ourselves.
