Well, there it is true that our surroundings, the people around us do create our mind. And it is true too when we did something uncommon we’ll be seen as weird man. But do you ever think to yourself why do you do it? Or you just follow the flow, do the things no matter whether they are good or bad according to the custom.
Sorry to say it, but I think do something you don’t really understand why you have to do it is a stupidity. A smart one knows what does he do, why does he do it, and the purpose of doing it.
Only two things are infinite: the universe and human stupidity. And I am not sure about the former.
