At bottom every man knows well enough that he is a unique being, only once on this earth; and by no extraordinary chance will such a marvelously picturesque piece of diversity in unity as he is, ever be put together a second time.
uniquequotes
To be oneself, simply oneself, is so amazing and utterly unique an experience that it’s hard to convince oneself so singular a thing happens to everybody.
Even if one is neither vain nor self-obsessed, it is so extraordinary to be oneself – exactly oneself and no one else – and so unique, that it seems natural that one should also be unique for someone else.
