Idiot was originally created to refer to a person without professional skill. Over time the word "Idiot" was shifted to the original meaning and came to refer to individuals with overall bad judgment–individuals who are "stupid".
It maybe a stupid thing for you but not for others. I am completely aware that some of the great people are called stupid in their times but their works are applauded today. I think they don't care at all.

I guess having stupidity is not bad at all. I mean, as human, we are just scared of stepping up because we know that we will be laughed at when we mess up. Don't that make us human at all? We all know humans are not the perfect being, so it is ok to be stupid.
