«Man is least himself when he talks in his own person. Give him a mask and he will tell you the truth»
   -Oscar Wilde

I can give you stories, I know them, every detail of them, they form into my head, then float through my neck, arm, hand and pen to come to you.

But I can't give you myself. Because I am not sure who that is, so I try to create myself. 

It is indeed hard to be a character, you can invent yourself all you want, however in the end, if it is not you, it will never be ok.
