If we go by the meaning, it means - someone with no special or distinctive features; someone who is normal. And therefore extraordinary is one who is Extra- Ordinary, that is, one who is too simple, too ordinary, too normal.
We are not normal human beings, we are too complex, we are to cunning, too rigid, too much inclined towards this or that. We are always trying to achieve something, trying to be somebody with Name, Fame or Status & yet want to be treated as Extraordinary.
What is so extraordinary about all this, this is too common. To be extraordinary, one should have the courage to walk alone, to give up all the prejudices, to go beyond all attachments & yet serve all human beings with no pride in oneself, with no sense of achievement.
To be Ordinary is too difficult. It means to live without "I".
