No, I don't think so. In this world each and everyday we are learning something. Leaning is Universal .It is a life long process. It is one of the most important part of our life. It is totally wrong to say that I know everything .Yahh, I can say that I know about that particular thing. But can't say that I know everything. So day by day I am learning new things. So I would like to say that I don't know everything. But trying to learn as much as possible. Even no one in the world can say that he or she knows everything which is impossible. So everyone should try to learn something new. It is totally wrong to say that I know everything.Even it is not good to say that we know everything.
