Uniquenes

Firstly , Thanks buddy for asking the question that ' How can we say , we are unique ? '
So, Dear buddy ! Before you can say that , first have a deep view of what you are ?
Starting from your fingerprints to your problems , solutions, family , stories etc. Does these all matches with anyone around you ?
No, just because " You " were created only once. There was no " You " before you and there won't be another " You " after you.
This is 100% correct.

But, literally in another reality _ _ _
All these physical definitions of Uniqueness is a wakeup call and to make your subconscious believe and to help you to find your unique talent.         
  _ _ This is also true in someway or the other.

In better words uniqueness is , what nobody accept you can. And it is not the matter of a day. It takes time to work upon your uniqueness. To find it, To practice it and To make it perfect.
For better understanding,
Let's take the examples ,
Legendary Cricket of football players of all time. Or u can take any.
 ~ Now Just compare two great players of football or Cricket. And the difference you will find between them is there uniqueness.
~ All Those who play International Cricket or Football are the best lots. But only those who have something different in them, are remembered forever.

Yes, there can be the people , who are better than you right now. But your uniqueness will make you something different from the other. Something out of the box.
So, find out your that unique talent in which you are confident that, non can do, beside you.
Here the unique talent does not mean, you play a better football. Here talent mean the another best player doesn't play , like that of you.
 * The talent which becomes your identity is your Uniqueness. *
Remember for sure,
     ' If you try to be the Best , you will be
       No. 1   ........... But ,
       If you try to be Unique , you will be the only One. '
Hope i answered it well.
