The idea that everybody is unique has become a bit of a cliché, to say the least.  And, like most clichés, if you analyze what you’re actually saying, you quickly realize just how silly it is.  If we are all unique, then “uniqueness” is a common quality we all possess, and being unique becomes average, making nobody unique.  The entire concept of being unique is that it only works if everybody can’t be unique.  True, you could argue that everybody is different, but being different does not make you unique.

And while we’ve got “unique” on the spot, it is a word that requires no modification.  You can’t be “very unique” or “sort of unique” or “just a little unique” or what have you.  If something is unique, then that’s it.
